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 and are equivalent to `C-v' and +`M-v', just as they are in other modes. + + +File: xemacs.info, Node: Mark and Region, Next: General Calendar, Prev: Scroll Calendar, Up: Calendar/Diary + +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.

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.

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.
