CALENDAR(1) 386BSD Reference Manual CALENDAR(1)
NAME
calendar - reminder service
SYNOPSIS
calendar [-a]
DESCRIPTION
Calendar checks the current directory for a file named named calendar and
displays lines that begin with either today's date or tomorrow's. On
Fridays, events on Friday through Monday are displayed.
The following options are available:
-a Process the ``calendar'' files of all users and mail the results
to them. This requires super-user privileges.
A month and day should begin lines. They may be entered in almost any
format, either numeric or as character strings. A single asterisk
(``*'') matches every month. A day without a month matches that day of
every week. A month without a day matches the first of that month. Two
numbers default to the month followed by the day. Lines with leading
tabs default to the last entered date, allowing multiple line
specifications for a single date. By convention, dates followed by an
asterisk are not fixed, i.e. change from year to year.
The ``calendar'' file is preprocessed by cpp(1), allowing the inclusion
of shared files such as company holidays or meetings. If the shared file
is not referenced by a full pathname, cpp(1) searches in the current (or
home) directory first, and then in the directory /usr/share/calendar.
Empty lines and lines protected by the C commenting syntax (/* ... */)
are ignored.
Some possible calendar entries:
#include <calendar.usholiday>
#include <calendar.birthday>
6/15 ... June 15 (if ambiguous, will default to month/day).
Jun. 15 ... June 15.
15 June ... June 15.
Thursday ... Every Thursday.
June ... Every June 1st.
15 * ... 15th of every month.
FILES
The following default calendar files are provided:
calendar.birthday Births and deaths of famous (and not-so-famous)
people.
calendar.christian Christian holidays. This calendar should be updated
yearly by the local system administrator so that
roving holidays are set correctly for the current
year.
calendar.computer Days of special significance to computer people.
calendar.history Everything else, mostly U. S. historical events.
calendar.holiday Other holidays, including the not-well-known,
obscure, and really obscure.
calendar.judaic Jewish holidays. This calendar should be updated
yearly by the local system administrator so that
roving holidays are set correctly for the current
year.

oriented toward rock 'n' roll.

yearly by the local system administrator so that
roving holidays are set correctly for the current
year.

COMPATIBILITY
The calendar program previously selected lines which had the correct date
anywhere in the line. This is no longer true, the date is only
recognized when it occurs first on the line.
HISTORY
A calendar command appeared in Version 7 AT&T UNIX.
BUGS
Calendar doesn't handle events that move around from year to year, i.e.
``the last Monday in April''.
