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 the calendar means moving the strip horizontally, so that new months become visible in the window.
Scroll calendar one month forward (calendar-scroll-left).
Scroll calendar one month backward (calendar-scroll-right).
Scroll the calendar forward (calendar-scroll-calendar-left).
Scroll the calendar backward (calendar-scroll-calendar-right).
Recenter the date at point.
The most basic calendar scroll commands scroll by one month at a time.
> (calendar-scroll-left) scrolls the calendar contents one
month forward in time. < (calendar-scroll-right) scrolls
the contents one month backwards in time.
The commands C-v (calendar-scroll-calendar-left) and
M-v (calendar-scroll-calendar-right) scroll the
calendar by an entire screen—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.
The function keys PageDown (or next) and PageUp (or prior) are equivalent to C-v and M-v, just as they are in other modes.
The command C-l (calendar-recenter) scrolls the calendar
on display so that the month of the date at point is centered
horizontally. Next invocation of this command puts that month on the
leftmost position, and another invocation puts it on the rightmost
position. Subsequent invocations reuse the same order in a cyclical
manner.
