On Fridays, events on Friday through Monday are displayed. .Pp The options are as follows: .Bl -tag -width Ds .It Fl a Process the .Dq calendar files of all users and mail the results to them. This requires superuser privileges. .It Fl A Ar num Print lines from today and next .Ar num days (forward, future). .It Fl b Enforce special date calculation mode for KOI8 calendars. .It Fl B Ar num Print lines from today and previous .Ar num days (backward, past). .It Fl f Pa calendarfile Use .Pa calendarfile as the default calendar file. .It Fl t Ar [[[cc]yy][mm]]dd Act like the specified value is .Dq today instead of using the current date. .El .Pp To handle calendars in your national code table you can specify .Dq LANG= in the calendar file as early as possible. To handle national Easter names in the calendars, .Dq Easter= (for Catholic Easter) or .Dq Paskha= (for Orthodox Easter) can be used. .Pp To enforce special date calculation mode for Cyrillic calendars you should specify .Dq LANG= and .Dq BODUN= where can be ru_RU.KOI8-R, uk_UA.KOI8-U or by_BY.KOI8-B. .Pp Other lines should begin with a month and day. They may be entered in almost any format, either numeric or as character strings. If proper locale is set, national months and weekdays names can be used. 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. .Dq Easter (may be followed by a positive or negative integer) is Easter for this year. .Dq Paskha (may be followed by a positive or negative integer) is Orthodox Easter for this year. Weekdays may be followed by .Dq -4 .Li ... .Dq +5 (aliases last, first, second, third, fourth) for moving events like .Dq the last Monday in April . .Pp By convention, dates followed by an asterisk .Pq Sq * are not fixed, i.e., change from year to year. .Pp Day descriptions start after the first character in the line; if the line does not contain a character, it isn't printed out. If the first character in the line is a character, it is treated as the continuation of the previous description. .Pp The calendar file is preprocessed by .Xr 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, .Xr cpp 1 searches in the current (or home) directory first, and then in the directory .Pa /usr/share/calendar . Empty lines and lines protected by the C commenting syntax .Pq Li /* ... */ are ignored. .Pp Some possible calendar entries ( characters are highlighted by a \fB\et\fR sequence): .Bd -unfilled -offset indent LANG=C Easter=Ostern #include #include 6/15\fB\et\fRJune 15 (if ambiguous, will default to month/day).

This is no longer true: the date is only recognized when it occurs at the beginning of a line. .Sh HISTORY A .Nm command appeared in .At v7 . .Sh BUGS .Nm doesn't handle Jewish holidays or moon phases.
