Return to calendar.h CVS log

Up to [local] / src / usr.bin / calendar

Show periodic events the correct number of times.
Calculate special events (Easter) correctly regardless of which year
they occur in (thus fixing user/562).
Keep locales and special event names from propogating from one user
to the next during "calendar -a".
Set up a framework to handle special events other than Easter (for instance,
Jewish events, eventually).
Various other fixes.
