+
+Mail Mode
+=========
+
+ The major mode used in the `*mail*' buffer is Mail mode. Mail mode
+is similar to Text mode, but several commands are provided on the `C-c'
+prefix. These commands all deal specifically with editing or sending
+the message.
+
+`C-c C-s'
+ Send the message, and leave the `*mail*' buffer selected
+ (`mail-send').
+
+`C-c C-c'
+ Send the message, and select some other buffer
+ (`mail-send-and-exit').
+
+`C-c C-f C-t'
+ Move to the `To' header field, creating one if there is none
+ (`mail-to').
+
+`C-c C-f C-s'
+ Move to the `Subject' header field, creating one if there is none
+ (`mail-subject').
+
+`C-c C-f C-c'
+ Move to the `CC' header field, creating one if there is none
+ (`mail-cc').
+
+`C-c C-w'
+ Insert the file `~/.signature' at the end of the message text
+ (`mail-signature').
+
+`C-c C-y'
+ Yank the selected message (`mail-yank-original').
+
+`C-c C-q'
+ Fill all paragraphs of yanked old messages, each individually
+ (`mail-fill-yanked-message').
+
+`<button3>'
+ Pops up a menu of useful mail-mode commands.
+
+ There are two ways to send a message. `C-c C-c'
+(`mail-send-and-exit') is the usual way to send the message. It sends
+the message and then deletes the window (if there is another window) or
+switches to another buffer. It puts the `*mail*' buffer at the lowest
+priority for automatic reselection, since you are finished with using
+it. `C-c C-s' (`mail-send') sends the message and marks the `*mail*'
+buffer unmodified, but leaves that buffer selected so that you can
+modify the message (perhaps with new recipients) and send it again.
+
+ Mail mode provides some other special commands that are useful for
+editing the headers and text of the message before you send it. There
+are three commands defined to move point to particular header fields,
+all based on the prefix `C-c C-f' (`C-f' is for "field"). They are
+`C-c C-f C-t' (`mail-to') to move to the `To' field, `C-c C-f C-s'
+(`mail-subject') for the `Subject' field, and `C-c C-f C-c' (`mail-cc')
+for the `CC' field. These fields have special motion commands because
+they are edited most frequently.
+
+ `C-c C-w' (`mail-signature') adds a standard piece of text at the
+end of the message to say more about who you are. The text comes from
+the file `.signature' in your home directory.
+
+ When you use an Rmail command to send mail from the Rmail mail
+reader, you can use `C-c C-y' `mail-yank-original' inside the `*mail*'
+buffer to insert the text of the message you are replying to. Normally
+Rmail indents each line of that message four spaces and eliminates most
+header fields. A numeric argument specifies the number of spaces to
+indent. An argument of just `C-u' says not to indent at all and not to
+eliminate anything. `C-c C-y' always uses the current message from the
+`RMAIL' buffer, so you can insert several old messages by selecting one
+in `RMAIL', switching to `*mail*' and yanking it, then switching back
+to `RMAIL' to select another.
+
+ After using `C-c C-y', you can use the command `C-c C-q'
+(`mail-fill-yanked-message') to fill the paragraphs of the yanked old
+message or messages. One use of `C-c C-q' fills all such paragraphs,
+each one separately.
+
+ Clicking the right mouse button in a mail buffer pops up a menu of
+the above commands, for easy access.
+
+ Turning on Mail mode (which `C-x m' does automatically) calls the
+value of `text-mode-hook', if it is not void or `nil', and then calls
+the value of `mail-mode-hook' if that is not void or `nil'.

+
+Reading Mail
+************
+
+ XEmacs provides three separate mail-reading packages. Each one
+comes with its own manual, which is included standard with the XEmacs
+distribution.
+
+ The recommended mail-reading package for new users is VM. VM works
+with standard Unix-mail-format folders and was designed as a replacement
+for the older Rmail.
+
+ XEmacs also provides a sophisticated and comfortable front-end to the
+MH mail-processing system, called `mh-e'. Unlike in other mail
+programs, folders in MH are stored as file-system directories, with
+each message occupying one (numbered) file. This facilitates working
+with mail using shell commands, and many other features of MH are also
+designed to integrate well with the shell and with shell scripts. Keep
+in mind, however, that in order to use mh-e you must have the MH
+mail-processing system installed on your computer.
+
+ Finally, XEmacs provides the Rmail package. Rmail is (currently) the
+only mail reading package distributed with FSF GNU Emacs, and is
+powerful in its own right. However, it stores mail folders in a special
+format called `Babyl', that is incompatible with all other
+frequently-used mail programs. A utility program is provided for
+converting Babyl folders to standard Unix-mail format; however, unless
+you already have mail in Babyl-format folders, you should consider
+using VM or mh-e instead. (If at times you have to use FSF Emacs, it is
+not hard to obtain and install VM for that editor.)

+Calendar Mode and the Diary
+===========================
+
+ Emacs provides the functions of a desk calendar, with a diary of
+planned or past events. To enter the calendar, type `M-x calendar';
+this displays a three-month calendar centered on the current month, with
+point on the current date. With a numeric argument, as in `C-u M-x
+calendar', it prompts you for the month and year to be the center of the
+three-month calendar. The calendar uses its own buffer, whose major
+mode is Calendar mode.
+
+ `Button2' in the calendar brings up a menu of operations on a
+particular date; `Buttons3' brings up a menu of commonly used calendar
+features that are independent of any particular date. To exit the
+calendar, type `q'. *Note Customizing the Calendar and Diary:

+Movement in the Calendar
+------------------------
+
+ Calendar mode lets you move through the calendar in logical units of
+time such as days, weeks, months, and years. If you move outside the
+three months originally displayed, the calendar display "scrolls"
+automatically through time to make the selected date visible. Moving to
+a date lets you view its holidays or diary entries, or convert it to
+other calendars; moving longer time periods is also useful simply to
+scroll the calendar.

+
+Motion by Integral Days, Weeks, Months, Years
+.............................................
+
+ The commands for movement in the calendar buffer parallel the
+commands for movement in text. You can move forward and backward by
+days, weeks, months, and years.
+
+`C-f'
+ Move point one day forward (`calendar-forward-day').
+
+`C-b'
+ Move point one day backward (`calendar-backward-day').
+
+`C-n'
+ Move point one week forward (`calendar-forward-week').
+
+`C-p'
+ Move point one week backward (`calendar-backward-week').
+
+`M-}'
+ Move point one month forward (`calendar-forward-month').
+
+`M-{'
+ Move point one month backward (`calendar-backward-month').
+
+`C-x ]'
+ Move point one year forward (`calendar-forward-year').
+
+`C-x ['
+ Move point one year backward (`calendar-backward-year').
+
+ The day and week commands are natural analogues of the usual Emacs
+commands for moving by characters and by lines. Just as `C-n' usually
+moves to the same column in the following line, in Calendar mode it
+moves to the same day in the following week. And `C-p' moves to the
+same day in the previous week.
+
+ The arrow keys are equivalent to `C-f', `C-b', `C-n' and `C-p', just
+as they normally are in other modes.
+
+ The commands for motion by months and years work like those for
+weeks, but move a larger distance. The month commands `M-}' and `M-{'
+move forward or backward by an entire month's time. The year commands
+`C-x ]' and `C-x [' move forward or backward a whole year.
+
+ The easiest way to remember these commands is to consider months and
+years analogous to paragraphs and pages of text, respectively. But the
+commands themselves are not quite analogous. The ordinary Emacs
+paragraph commands move to the beginning or end of a paragraph, whereas
+these month and year commands move by an entire month or an entire
+year, which usually involves skipping across the end of a month or year.
+
+ All these commands accept a numeric argument as a repeat count. For
+convenience, the digit keys and the minus sign specify numeric
+arguments in Calendar mode even without the Meta modifier. For example,
+`100 C-f' moves point 100 days forward from its present location.
+
+\1f
+File: xemacs.info, Node: Move to Beginning or End, Next: Specified Dates, Prev: Calendar Unit Motion, Up: Calendar Motion
+
+Beginning or End of Week, Month or Year
+.......................................
+
+ A week (or month, or year) is not just a quantity of days; we think
+of weeks (months, years) as starting on particular dates. So Calendar
+mode provides commands to move to the beginning or end of a week, month
+or year:
+
+`C-a'
+ Move point to start of week (`calendar-beginning-of-week').
+
+`C-e'
+ Move point to end of week (`calendar-end-of-week').
+
+`M-a'
+ Move point to start of month (`calendar-beginning-of-month').
+
+`M-e'
+ Move point to end of month (`calendar-end-of-month').
+
+`M-<'
+ Move point to start of year (`calendar-beginning-of-year').
+
+`M->'
+ Move point to end of year (`calendar-end-of-year').
+
+ These commands also take numeric arguments as repeat counts, with the
+repeat count indicating how many weeks, months, or years to move
+backward or forward.
+
+ By default, weeks begin on Sunday. To make them begin on Monday
+instead, set the variable `calendar-week-start-day' to 1.
+

+File: xemacs.info, Node: Specified Dates, Prev: Move to Beginning or End, Up: Calendar Motion
+
+Particular Dates
+................
+
+ Calendar mode provides commands for moving to a particular date
+specified in various ways.
+
+`g d'
+ Move point to specified date (`calendar-goto-date').
+
+`o'
+ Center calendar around specified month (`calendar-other-month').
+
+`.'
+ Move point to today's date (`calendar-goto-today').
+
+ `g d' (`calendar-goto-date') prompts for a year, a month, and a day
+of the month, and then moves to that date. Because the calendar
+includes all dates from the beginning of the current era, you must type
+the year in its entirety; that is, type `1990', not `90'.
+
+ `o' (`calendar-other-month') prompts for a month and year, then
+centers the three-month calendar around that month.
+
+ You can return to today's date with `.' (`calendar-goto-today').
+

+File: xemacs.info, Node: Scroll Calendar, Next: Mark and Region, Prev: Calendar Motion, Up: Calendar/Diary
+
+Scrolling the Calendar through Time
+-----------------------------------
+
+ The calendar display scrolls automatically through time when you
+move out of the visible portion. You can also scroll it manually.
+Imagine that the calendar window contains a long strip of paper with
+the months on it. Scrolling it means moving the strip so that new
+months become visible in the window.
+
+`C-x <'
+ Scroll calendar one month forward (`scroll-calendar-left').
+
+`C-x >'
+ Scroll calendar one month backward (`scroll-calendar-right').
+
+`C-v'
+`<NEXT>'
+ Scroll calendar three months forward
+ (`scroll-calendar-left-three-months').
+
+`M-v'
+`<PRIOR>'
+ Scroll calendar three months backward
+ (`scroll-calendar-right-three-months').
+
+ The most basic calendar scroll commands scroll by one month at a
+time. This means that there are two months of overlap between the
+display before the command and the display after. `C-x <' scrolls the
+calendar contents one month to the left; that is, it moves the display
+forward in time. `C-x >' scrolls the contents to the right, which
+moves backwards in time.
+
+ The commands `C-v' and `M-v' scroll the calendar by an entire
+"screenful"--three months--in analogy with the usual meaning of these
+commands. `C-v' makes later dates visible and `M-v' makes earlier
+dates visible. These commands take a numeric argument as a repeat
+count; in particular, since `C-u' multiplies the next command by four,
+typing `C-u C-v' scrolls the calendar forward by a year and typing `C-u
+M-v' scrolls the calendar backward by a year.
+
+ The function keys <NEXT> and <PRIOR> are equivalent to `C-v' and
+`M-v', just as they are in other modes.
+

+
+The Mark and the Region
+-----------------------
+
+ The concept of the mark applies to the calendar just as to any other
+buffer, but it marks a _date_, not a _position_ in the buffer. The
+region consists of the days between the mark and point (including the
+starting and stopping dates).
+
+`C-SPC'
+ Set the mark to today's date (`calendar-set-mark').
+
+`C-@'
+ The same.
+
+`C-x C-x'
+ Interchange mark and point (`calendar-exchange-point-and-mark').
+
+`M-='
+ Display the number of days in the current region
+ (`calendar-count-days-region').
+
+ You set the mark in the calendar, as in any other buffer, by using
+`C-@' or `C-SPC' (`calendar-set-mark'). You return to the marked date
+with the command `C-x C-x' (`calendar-exchange-point-and-mark') which
+puts the mark where point was and point where mark was. The calendar
+is scrolled as necessary, if the marked date was not visible on the
+screen. This does not change the extent of the region.
+
+ To determine the number of days in the region, type `M-='
+(`calendar-count-days-region'). The numbers of days printed is
+_inclusive_; that is, it includes the days specified by mark and point.
+
+ The main use of the mark in the calendar is to remember dates that
+you may want to go back to. To make this feature more useful, the mark
+ring (*note Mark Ring::) operates exactly as in other buffers: Emacs
+remembers 16 previous locations of the mark. To return to a marked
+date, type `C-u C-SPC' (or `C-u C-@'); this is the command
+`calendar-set-mark' given a numeric argument. It moves point to where
+the mark was, restores the mark from the ring of former marks, and
+stores the previous point at the end of the mark ring. So, repeated
+use of this command moves point through all the old marks on the ring,
+one by one.

+Miscellaneous Calendar Commands
+-------------------------------
+
+`p d'
+ Display day-in-year (`calendar-print-day-of-year').
+
+`?'
+ Briefly describe calendar commands (`describe-calendar-mode').
+
+`C-c C-l'
+ Regenerate the calendar window (`redraw-calendar').
+
+`SPC'
+ Scroll the next window (`scroll-other-window').
+
+`q'
+ Exit from calendar (`exit-calendar').
+
+ If you want to know how many days have elapsed since the start of
+the year, or the number of days remaining in the year, type the `p d'
+command (`calendar-print-day-of-year'). This displays both of those
+numbers in the echo area.
+
+ To display a brief description of the calendar commands, type `?'
+(`describe-calendar-mode'). For a fuller description, type `C-h m'.
+
+ You can use `SPC' (`scroll-other-window') to scroll the other
+window. This is handy when you display a list of holidays or diary
+entries in another window.
+
+ If the calendar window text gets corrupted, type `C-c C-l'
+(`redraw-calendar') to redraw it. (This can only happen if you use
+non-Calendar-mode editing commands.)
+
+ In Calendar mode, you can use `SPC' (`scroll-other-window') to
+scroll the other window. This is handy when you display a list of
+holidays or diary entries in another window.
+
+ To exit from the calendar, type `q' (`exit-calendar'). This buries
+all buffers related to the calendar, selecting other buffers. (If a
+frame contains a dedicated calendar window, exiting from the calendar
+iconifies that frame.)

+
+`t m'
+ Generate a one-month calendar (`cal-tex-cursor-month').
+

+ (`cal-tex-cursor-year-landscape').
+
+`t f y'
+ Generate a Filofax-style calendar for one year
+ (`cal-tex-cursor-filofax-year').
+
+ Some of these commands print the calendar sideways (in "landscape
+mode"), so it can be wider than it is long. Some of them use Filofax
+paper size (3.75in x 6.75in). All of these commands accept a prefix
+argument which specifies how many days, weeks, months or years to print
+(starting always with the selected one).
+
+ If the variable `cal-tex-holidays' is non-`nil' (the default), then
+the printed calendars show the holidays in `calendar-holidays'. If the
+variable `cal-tex-diary' is non-`nil' (the default is `nil'), diary
+entries are included also (in weekly and monthly calendars only).

+
+Holidays
+--------
+
+ The Emacs calendar knows about all major and many minor holidays,
+and can display them.
+
+`h'
+ Display holidays for the selected date
+ (`calendar-cursor-holidays').
+
+`Button2 Holidays'
+ Display any holidays for the date you click on.
+
+`x'
+ Mark holidays in the calendar window (`mark-calendar-holidays').
+
+`u'
+ Unmark calendar window (`calendar-unmark').
+
+`a'
+ List all holidays for the displayed three months in another window
+ (`list-calendar-holidays').
+
+`M-x holidays'
+ List all holidays for three months around today's date in another
+ window.
+
+`M-x list-holidays'
+ List holidays in another window for a specified range of years.
+
+ To see if any holidays fall on a given date, position point on that
+date in the calendar window and use the `h' command. Alternatively,
+click on that date with `Button2' and then choose `Holidays' from the
+menu that appears. Either way, this displays the holidays for that
+date, in the echo area if they fit there, otherwise in a separate
+window.
+
+ To view the distribution of holidays for all the dates shown in the
+calendar, use the `x' command. This displays the dates that are
+holidays in a different face (or places a `*' after these dates, if
+display with multiple faces is not available). The command applies both
+to the currently visible months and to other months that subsequently
+become visible by scrolling. To turn marking off and erase the current
+marks, type `u', which also erases any diary marks (*note Diary::).
+
+ To get even more detailed information, use the `a' command, which
+displays a separate buffer containing a list of all holidays in the
+current three-month range. You can use <SPC> in the calendar window to
+scroll that list.
+
+ The command `M-x holidays' displays the list of holidays for the
+current month and the preceding and succeeding months; this works even
+if you don't have a calendar window. If you want the list of holidays
+centered around a different month, use `C-u M-x holidays', which
+prompts for the month and year.
+
+ The holidays known to Emacs include United States holidays and the
+major Christian, Jewish, and Islamic holidays; also the solstices and
+equinoxes.
+
+ The command `M-x list-holidays' displays the list of holidays for a
+range of years. This function asks you for the starting and stopping
+years, and allows you to choose all the holidays or one of several
+categories of holidays. You can use this command even if you don't have
+a calendar window.
+
+ The dates used by Emacs for holidays are based on _current
+practice_, not historical fact. Historically, for instance, the start
+of daylight savings time and even its existence have varied from year to
+year, but present United States law mandates that daylight savings time
+begins on the first Sunday in April. When the daylight savings rules
+are set up for the United States, Emacs always uses the present
+definition, even though it is wrong for some prior years.

-
-Commands to Add to the Diary
-----------------------------
-
- While in the calendar, there are several commands to create diary
-entries:
-
-`i d'
- Add a diary entry for the selected date (`insert-diary-entry').
-
-`i w'
- Add a diary entry for the selected day of the week
- (`insert-weekly-diary-entry').
-
-`i m'
- Add a diary entry for the selected day of the month
- (`insert-monthly-diary-entry').
-
-`i y'
- Add a diary entry for the selected day of the year
- (`insert-yearly-diary-entry').
-
- You can make a diary entry for a specific date by selecting that date
-in the calendar window and typing the `i d' command. This command
-displays the end of your diary file in another window and inserts the
-date; you can then type the rest of the diary entry.
-
- If you want to make a diary entry that applies to a specific day of
-the week, select that day of the week (any occurrence will do) and type
-`i w'. This inserts the day-of-week as a generic date; you can then
-type the rest of the diary entry. You can make a monthly diary entry in
-the same fashion. Select the day of the month, use the `i m' command,
-and type rest of the entry. Similarly, you can insert a yearly diary
-entry with the `i y' command.
-
- All of the above commands make marking diary entries by default. To
-make a nonmarking diary entry, give a numeric argument to the command.
-For example, `C-u i w' makes a nonmarking weekly diary entry.
-
- When you modify the diary file, be sure to save the file before
-exiting Emacs.

-Special Diary Entries
----------------------
-
- In addition to entries based on calendar dates, the diary file can
-contain "sexp entries" for regular events such as anniversaries. These
-entries are based on Lisp expressions (sexps) that Emacs evaluates as
-it scans the diary file. Instead of a date, a sexp entry contains `%%'
-followed by a Lisp expression which must begin and end with
-parentheses. The Lisp expression determines which dates the entry
-applies to.
-
- Calendar mode provides commands to insert certain commonly used sexp
-entries:
-
-`i a'
- Add an anniversary diary entry for the selected date
- (`insert-anniversary-diary-entry').
-
-`i b'
- Add a block diary entry for the current region
- (`insert-block-diary-entry').
-
-`i c'
- Add a cyclic diary entry starting at the date
- (`insert-cyclic-diary-entry').
-
- If you want to make a diary entry that applies to the anniversary of
-a specific date, move point to that date and use the `i a' command.
-This displays the end of your diary file in another window and inserts
-the anniversary description; you can then type the rest of the diary
-entry. The entry looks like this:
-
- The effect of `i a' is to add a `diary-anniversary' sexp to your
-diary file. You can also add one manually, for instance:
-
- %%(diary-anniversary 10 31 1948) Arthur's birthday
-
-This entry applies to October 31 in any year after 1948; `10 31 1948'
-specifies the date. (If you are using the European calendar style, the
-month and day are interchanged.) The reason this expression requires a
-beginning year is that advanced diary functions can use it to calculate
-the number of elapsed years.
-
- A "block" diary entry applies to a specified range of consecutive
-dates. Here is a block diary entry that applies to all dates from June
-24, 1990 through July 10, 1990:
-
- %%(diary-block 6 24 1990 7 10 1990) Vacation
-
-The `6 24 1990' indicates the starting date and the `7 10 1990'
-indicates the stopping date. (Again, if you are using the European
-calendar style, the month and day are interchanged.)
-
- To insert a block entry, place point and the mark on the two dates
-that begin and end the range, and type `i b'. This command displays
-the end of your diary file in another window and inserts the block
-description; you can then type the diary entry.
-
- "Cyclic" diary entries repeat after a fixed interval of days. To
-create one, select the starting date and use the `i c' command. The
-command prompts for the length of interval, then inserts the entry,
-which looks like this:
-
- %%(diary-cyclic 50 3 1 1990) Renew medication
-
-This entry applies to March 1, 1990 and every 50th day following; `3 1
-1990' specifies the starting date. (If you are using the European
-calendar style, the month and day are interchanged.)
-
- All three of these commands make marking diary entries. To insert a
-nonmarking entry, give a numeric argument to the command. For example,
-`C-u i a' makes a nonmarking anniversary diary entry.
-
- Marking sexp diary entries in the calendar is _extremely_
-time-consuming, since every date visible in the calendar window must be
-individually checked. So it's a good idea to make sexp diary entries
-nonmarking (with `&') when possible.
-
- Another sophisticated kind of sexp entry, a "floating" diary entry,
-specifies a regularly occurring event by offsets specified in days,
-weeks, and months. It is comparable to a crontab entry interpreted by
-the `cron' utility. Here is a nonmarking, floating diary entry that
-applies to the last Thursday in November:
-
- &%%(diary-float 11 4 -1) American Thanksgiving
-
-The 11 specifies November (the eleventh month), the 4 specifies Thursday
-(the fourth day of the week, where Sunday is numbered zero), and the -1
-specifies "last" (1 would mean "first", 2 would mean "second", -2 would
-mean "second-to-last", and so on). The month can be a single month or
-a list of months. Thus you could change the 11 above to `'(1 2 3)' and
-have the entry apply to the last Thursday of January, February, and
-March. If the month is `t', the entry applies to all months of the
-year.
-
- The sexp feature of the diary allows you to specify diary entries
-based on any Emacs Lisp expression. You can use the library of built-in
-functions or you can write your own functions. The built-in functions
-include the ones shown in this section, plus a few others (*note Sexp
-Diary Entries::).
-
- The generality of sexps lets you specify any diary entry that you can
-describe algorithmically. Suppose you get paid on the 21st of the month
-if it is a weekday, and to the Friday before if the 21st is on a
-weekend. The diary entry
-
- &%%(let ((dayname (calendar-day-of-week date))
- (day (car (cdr date))))
- (or (and (= day 21) (memq dayname '(1 2 3 4 5)))
- (and (memq day '(19 20)) (= dayname 5)))
- ) Pay check deposited
-
-to just those dates. This example illustrates how the sexp can depend
-on the variable `date'; this variable is a list (MONTH DAY YEAR) that
-gives the Gregorian date for which the diary entries are being found.
-If the value of the sexp is `t', the entry applies to that date. If
-the sexp evaluates to `nil', the entry does _not_ apply to that date.

-Customizing the Calendar
-........................
-
- If you set the variable `view-diary-entries-initially' to `t',
-calling up the calendar automatically displays the diary entries for
-the current date as well. The diary dates appear only if the current
-date is visible. If you add both of the following lines to your
-`.emacs' file:
-
- (setq view-diary-entries-initially t)
- (calendar)
-
-this displays both the calendar and diary windows whenever you start
-Emacs.
-
- Similarly, if you set the variable
-`view-calendar-holidays-initially' to `t', entering the calendar
-automatically displays a list of holidays for the current three-month
-period. The holiday list appears in a separate window.
-
- You can set the variable `mark-diary-entries-in-calendar' to `t' in
-order to mark any dates with diary entries. This takes effect whenever
-the calendar window contents are recomputed. There are two ways of
-marking these dates: by changing the face (*note Faces::), if the
-display supports that, or by placing a plus sign (`+') beside the date
-otherwise.
-
- Similarly, setting the variable `mark-holidays-in-calendar' to `t'
-marks holiday dates, either with a change of face or with an asterisk
-(`*').
-
- The variable `calendar-holiday-marker' specifies how to mark a date
-as being a holiday. Its value may be a character to insert next to the
-date, or a face name to use for displaying the date. Likewise, the
-variable `diary-entry-marker' specifies how to mark a date that has
-diary entries. The calendar creates faces named `holiday-face' and
-`diary-face' for these purposes; those symbols are the default values
-of these variables, when Emacs supports multiple faces on your terminal.
-
- The variable `calendar-load-hook' is a normal hook run when the
-calendar package is first loaded (before actually starting to display
-the calendar).
-
- Starting the calendar runs the normal hook
-`initial-calendar-window-hook'. Recomputation of the calendar display
-does not run this hook. But if you leave the calendar with the `q'
-command and reenter it, the hook runs again.
-
- The variable `today-visible-calendar-hook' is a normal hook run
-after the calendar buffer has been prepared with the calendar when the
-current date is visible in the window. One use of this hook is to
-replace today's date with asterisks; to do that, use the hook function
-`calendar-star-date'.
-
- (add-hook 'today-visible-calendar-hook 'calendar-star-date)
-
-Another standard hook function marks the current date, either by
-changing its face or by adding an asterisk. Here's how to use it:
-
- (add-hook 'today-visible-calendar-hook 'calendar-mark-today)
-
-The variable `calendar-today-marker' specifies how to mark today's
-date. Its value should be a character to insert next to the date or a
-face name to use for displaying the date. A face named
-`calendar-today-face' is provided for this purpose; that symbol is the
-default for this variable when Emacs supports multiple faces on your
-terminal.
-
-A similar normal hook, `today-invisible-calendar-hook' is run if the
-current date is _not_ visible in the window.

-Customizing the Holidays
-........................
-
- Emacs knows about holidays defined by entries on one of several
-lists. You can customize these lists of holidays to your own needs,
-adding or deleting holidays. The lists of holidays that Emacs uses are
-for general holidays (`general-holidays'), local holidays
-(`local-holidays'), Christian holidays (`christian-holidays'), Hebrew
-(Jewish) holidays (`hebrew-holidays'), Islamic (Moslem) holidays
-(`islamic-holidays'), and other holidays (`other-holidays').
-
- The general holidays are, by default, holidays common throughout the
-United States. To eliminate these holidays, set `general-holidays' to
-`nil'.
-
- There are no default local holidays (but sites may supply some). You
-can set the variable `local-holidays' to any list of holidays, as
-described below.
-
- By default, Emacs does not include all the holidays of the religions
-that it knows, only those commonly found in secular calendars. For a
-more extensive collection of religious holidays, you can set any (or
-all) of the variables `all-christian-calendar-holidays',
-`all-hebrew-calendar-holidays', or `all-islamic-calendar-holidays' to
-`t'. If you want to eliminate the religious holidays, set any or all
-of the corresponding variables `christian-holidays', `hebrew-holidays',
-and `islamic-holidays' to `nil'.
-
- You can set the variable `other-holidays' to any list of holidays.
-This list, normally empty, is intended for individual use.
-
- Each of the lists (`general-holidays', `local-holidays',
-`christian-holidays', `hebrew-holidays', `islamic-holidays', and
-`other-holidays') is a list of "holiday forms", each holiday form
-describing a holiday (or sometimes a list of holidays).
-
- Here is a table of the possible kinds of holiday form. Day numbers
-and month numbers count starting from 1, but "dayname" numbers count
-Sunday as 0. The element STRING is always the name of the holiday, as
-a string.
-
-`(holiday-fixed MONTH DAY STRING)'
- A fixed date on the Gregorian calendar. MONTH and DAY are
- numbers, STRING is the name of the holiday.
-
-`(holiday-float MONTH DAYNAME K STRING)'
- The Kth DAYNAME in MONTH on the Gregorian calendar (DAYNAME=0 for
- Sunday, and so on); negative K means count back from the end of
- the month. STRING is the name of the holiday.
-
-`(holiday-hebrew MONTH DAY STRING)'
- A fixed date on the Hebrew calendar. MONTH and DAY are numbers,
- STRING is the name of the holiday.
-
-`(holiday-islamic MONTH DAY STRING)'
- A fixed date on the Islamic calendar. MONTH and DAY are numbers,
- STRING is the name of the holiday.
-
-`(holiday-julian MONTH DAY STRING)'
- A fixed date on the Julian calendar. MONTH and DAY are numbers,
- STRING is the name of the holiday.
-
-`(holiday-sexp SEXP STRING)'
- A date calculated by the Lisp expression SEXP. The expression
- should use the variable `year' to compute and return the date of a
- holiday, or `nil' if the holiday doesn't happen this year. The
- value of SEXP must represent the date as a list of the form
- `(MONTH DAY YEAR)'. STRING is the name of the holiday.
-
-`(if CONDITION HOLIDAY-FORM &optional HOLIDAY-FORM)'
- A holiday that happens only if CONDITION is true.
-
-`(FUNCTION [ARGS])'
- A list of dates calculated by the function FUNCTION, called with
- arguments ARGS.
-
- For example, suppose you want to add Bastille Day, celebrated in
-France on July 14. You can do this by adding the following line to
-your `.emacs' file:
-
- (setq other-holidays '((holiday-fixed 7 14 "Bastille Day")))
-
-The holiday form `(holiday-fixed 7 14 "Bastille Day")' specifies the
-fourteenth day of the seventh month (July).
-
- Many holidays occur on a specific day of the week, at a specific time
-of month. Here is a holiday form describing Hurricane Supplication Day,
-celebrated in the Virgin Islands on the fourth Monday in August:
-
- (holiday-float 8 1 4 "Hurricane Supplication Day")
-
-Here the 8 specifies August, the 1 specifies Monday (Sunday is 0,
-Tuesday is 2, and so on), and the 4 specifies the fourth occurrence in
-the month (1 specifies the first occurrence, 2 the second occurrence,
--1 the last occurrence, -2 the second-to-last occurrence, and so on).
-
- You can specify holidays that occur on fixed days of the Hebrew,
-Islamic, and Julian calendars too. For example,
-
- (setq other-holidays
- '((holiday-hebrew 10 2 "Last day of Hanukkah")
- (holiday-islamic 3 12 "Mohammed's Birthday")
- (holiday-julian 4 2 "Jefferson's Birthday")))
-
-adds the last day of Hanukkah (since the Hebrew months are numbered with
-1 starting from Nisan), the Islamic feast celebrating Mohammed's
-birthday (since the Islamic months are numbered from 1 starting with
-Muharram), and Thomas Jefferson's birthday, which is 2 April 1743 on the
-Julian calendar.
-
- To include a holiday conditionally, use either Emacs Lisp's `if' or
-the `holiday-sexp' form. For example, American presidential elections
-occur on the first Tuesday after the first Monday in November of years
-divisible by 4:
-
- (holiday-sexp (if (= 0 (% year 4))
- (calendar-gregorian-from-absolute
- (1+ (calendar-dayname-on-or-before
- 1 (+ 6 (calendar-absolute-from-gregorian
- (list 11 1 year))))))
- "US Presidential Election"))
-
-or
-
- (if (= 0 (% displayed-year 4))
- (fixed 11
- (extract-calendar-day
- (calendar-gregorian-from-absolute
- (1+ (calendar-dayname-on-or-before
- 1 (+ 6 (calendar-absolute-from-gregorian
- (list 11 1 displayed-year)))))))
- "US Presidential Election"))
-
- Some holidays just don't fit into any of these forms because special
-calculations are involved in their determination. In such cases you
-must write a Lisp function to do the calculation. To include eclipses,
-for example, add `(eclipses)' to `other-holidays' and write an Emacs
-Lisp function `eclipses' that returns a (possibly empty) list of the
-relevant Gregorian dates among the range visible in the calendar
-window, with descriptive strings, like this:
-
- (((6 27 1991) "Lunar Eclipse") ((7 11 1991) "Solar Eclipse") ... )

-Date Display Format
-...................
-
- You can customize the manner of displaying dates in the diary, in
-mode lines, and in messages by setting `calendar-date-display-form'.
-This variable holds a list of expressions that can involve the variables
-`month', `day', and `year', which are all numbers in string form, and
-`monthname' and `dayname', which are both alphabetic strings. In the
-American style, the default value of this list is as follows:
-
- ((if dayname (concat dayname ", ")) monthname " " day ", " year)
-
-while in the European style this value is the default:
-
- ((if dayname (concat dayname ", ")) day " " monthname " " year)
-
- + The ISO standard date representation is this:
-
- (year "-" month "-" day)
-
-This specifies a typical American format:
-
- (month "/" day "/" (substring year -2))

-
-Time Display Format
-...................
-
- The calendar and diary by default display times of day in the
-conventional American style with the hours from 1 through 12, minutes,
-and either `am' or `pm'. If you prefer the European style, also known
-in the US as military, in which the hours go from 00 to 23, you can
-alter the variable `calendar-time-display-form'. This variable is a
-list of expressions that can involve the variables `12-hours',
-`24-hours', and `minutes', which are all numbers in string form, and
-`am-pm' and `time-zone', which are both alphabetic strings. The
-default value of `calendar-time-display-form' is as follows:
-
- (12-hours ":" minutes am-pm
- (if time-zone " (") time-zone (if time-zone ")"))
-
-Here is a value that provides European style times:
-
- (24-hours ":" minutes
- (if time-zone " (") time-zone (if time-zone ")"))
-
-gives military-style times like `21:07 (UT)' if time zone names are
-defined, and times like `21:07' if they are not.

-
-Daylight Savings Time
-.....................
-
- Emacs understands the difference between standard time and daylight
-savings time--the times given for sunrise, sunset, solstices,
-equinoxes, and the phases of the moon take that into account. The rules
-for daylight savings time vary from place to place and have also varied
-historically from year to year. To do the job properly, Emacs needs to
-know which rules to use.
-
- Some operating systems keep track of the rules that apply to the
-place where you are; on these systems, Emacs gets the information it
-needs from the system automatically. If some or all of this
-information is missing, Emacs fills in the gaps with the rules
-currently used in Cambridge, Massachusetts. If the resulting rules are
-not what you want, you can tell Emacs the rules to use by setting
-certain variables.
-
- If the default choice of rules is not appropriate for your location,
-you can tell Emacs the rules to use by setting the variables
-`calendar-daylight-savings-starts' and
-`calendar-daylight-savings-ends'. Their values should be Lisp
-expressions that refer to the variable `year', and evaluate to the
-Gregorian date on which daylight savings time starts or (respectively)
-ends, in the form of a list `(MONTH DAY YEAR)'. The values should be
-`nil' if your area does not use daylight savings time.
-
- Emacs uses these expressions to determine the starting date of
-daylight savings time for the holiday list and for correcting times of
-day in the solar and lunar calculations.
-
- The values for Cambridge, Massachusetts are as follows:
-
- (calendar-nth-named-day 1 0 4 year)
- (calendar-nth-named-day -1 0 10 year)
-
-That is, the first 0th day (Sunday) of the fourth month (April) in the
-year specified by `year', and the last Sunday of the tenth month
-(October) of that year. If daylight savings time were changed to start
-on October 1, you would set `calendar-daylight-savings-starts' to this:
-
- (list 10 1 year)
-
- For a more complex example, suppose daylight savings time begins on
-the first of Nisan on the Hebrew calendar. You should set
-`calendar-daylight-savings-starts' to this value:
-
- (calendar-gregorian-from-absolute
- (calendar-absolute-from-hebrew
- (list 1 1 (+ year 3760))))
-
-because Nisan is the first month in the Hebrew calendar and the Hebrew
-year differs from the Gregorian year by 3760 at Nisan.
-
- If there is no daylight savings time at your location, or if you want
-all times in standard time, set `calendar-daylight-savings-starts' and
-`calendar-daylight-savings-ends' to `nil'.
-
- The variable `calendar-daylight-time-offset' specifies the
-difference between daylight savings time and standard time, measured in
-minutes. The value for Cambridge, Massachusetts is 60.
-
- The two variables `calendar-daylight-savings-starts-time' and
-`calendar-daylight-savings-ends-time' specify the number of minutes
-after midnight local time when the transition to and from daylight
-savings time should occur. For Cambridge, Massachusetts both variables'
-values are 120.
