CALENDAR(1) FreeBSD General Commands Manual CALENDAR(1)
NAME
calendar -- reminder service
SYNOPSIS
calendar [-a] [-A num] [-B num] [-F friday] [-f calendarfile]
[-t dd[.mm[.year]]] [-W num]
DESCRIPTION
The calendar utility checks the current directory for a file named
calendar and displays lines that begin with either today's date or tomor-
row's. On the day before a weekend (normally Friday), events for the
next three days are displayed.
The following options are available:
-A num Print lines from today and the next num days (forward, future).
-a Process the ``calendar'' files of all users and mail the results
to them. This requires super-user privileges.
-B num Print lines from today and the previous num days (backward,
past).
-F friday
Specify which day of the week is ``Friday'' (the day before the
weekend begins). Default is 5.
-f calendarfile
Use calendarfile as the default calendar file.
-t dd[.mm[.year]]
For test purposes only: set date directly to argument values.
-W num Print lines from today and the next num days (forward, future).
Ignore weekends when calculating the number of days.
To handle calendars in your national code table you can specify
``LANG=<locale_name>'' in the calendar file as early as possible. To
handle national Easter names in the calendars ``Easter=<national_name>''
(for Catholic Easter) or ``Paskha=<national_name>'' (for Orthodox Easter)
can be used.
Other lines should begin with a month and day. They may be entered in
almost any format, either numeric or as character strings. If the proper
locale is set, national month and weekday 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.
``Easter'', is Easter for this year, and may be followed by a positive or
negative integer.
``Paskha'', is Orthodox Easter for this year, and may be followed by a
positive or negative integer.
Weekdays may be followed by ``-4'' ... ``+5'' (aliases for last, first,
second, third, fourth) for moving events like ``the last Monday in
April''.
By convention, dates followed by an asterisk are not fixed, i.e., change
from year to year.
Day descriptions start after the first <tab> character in the line; if
the line does not contain a <tab> character, it is not displayed. If the
first character in the line is a <tab> character, it is treated as a con-
tinuation of the previous line.
The ``calendar'' file is preprocessed by cpp(1), allowing the inclusion
of shared files such as lists of 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 (<tab> characters highlighted by \t
sequence)

nized when it occurs at the beginning of a line.

BUGS
The calendar utility doesn't handle Jewish holidays and moon phases.
