NAME

     calendar -- reminder service

SYNOPSIS

     calendar [-ab] [-A num] [-B num] [-l num] [-w num] [-f calendarfile] [-t [[[cc]yy][mm]]dd]

DESCRIPTION

     The calendar utility checks the current directory or the directory specified by the CALENDAR_DIR environment variable for a file 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 options are as follows:

     -A num  Print lines from today and next num days (forward, future). Defaults to one.

     -a      Process the ``calendar'' files of all users and mail the results to them.	This requires superuser privileges.

     -B num  Print lines from today and previous num days (backward, past).

     -b      Enforce special date calculation mode for KOI8 calendars.

     -l num  Print lines from today and next num days (forward, future). Defaults to one.

     -w num  Print lines from today and next num days, only if today is Friday (forward, future). Defaults to two, which causes calendar to print
	     entries through the weekend on Fridays.

     -f calendarfile
	     Use calendarfile as the default calendar file.

     -t [[[cc]yy][mm]]dd
	     Act like the specified value is ``today'' instead of using the current date.

     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.

     A special locale name exists: 'utf-8'.  Specifying ``LANG=utf-8'' indicates that the dates will be read using the C locale, and the descrip-
     tions will be encoded in UTF-8.  This is usually used for the distributed calendar files.	The ``CALENDAR'' variable can be used to specify
     the style.  Only 'Julian' and 'Gregorian' styles are currently supported.	Use ``CALENDAR='' to return to the default (Gregorian).

     To enforce special date calculation mode for Cyrillic calendars you should specify ``LANG=<local_name>'' and ``BODUN=<bodun_prefix>'' where
     <local_name> can be ru_RU.KOI8-R, uk_UA.KOI8-U or by_BY.KOI8-B.

     Note that the locale is reset to the user's default for each new file that is read. This is so that locales from one file do not accidentally
     carry over into another file.

     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.  ``Easter'' (may be followed by
     a positive or negative integer) is Easter for this year.  ``Paskha'' (may be followed by a positive or negative integer) is Orthodox Easter
     for this year.  Weekdays may be followed by ``-4'' ... ``+5'' (aliases 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 isn't printed out.	If
     the first character in the line is a <tab> character, it is treated as the continuation of the previous description.

     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 directory
     /etc/calendar, and finally in /usr/share/calendar.  Empty lines and lines protected by the C commenting syntax (/* ... */) are ignored.

     Some possible calendar entries (a 	 sequence denotes a <tab> character):

	   LANG=C
	   Easter=Ostern

	   #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.

	   May Sun+2	second Sunday in May (Muttertag)
	   04/SunLast	last Sunday in April,
	   	summer time in Europe
	   Easter	Easter
	   Ostern-2	Good Friday (2 days before Easter)
	   Paskha	Orthodox Easter

STANDARDS

     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 at the beginning of a line.

COMPATIBILITY

     The calendar command will only display lines that use a <tab> character to separate the date and description, or that begin with a <tab>.
     This is different than in previous releases.

     The -t flag argument syntax is from the original FreeBSD calendar program.

     The -l and -w flags are Debian-specific enhancements. Also, the original calendar program did not accept 0 as an argument to the -A flag.

     Using 'utf-8' as a locale name is a Debian-specific enhancement.

HISTORY

     A calendar command appeared in Version 7 AT&T UNIX.

BUGS

     calendar doesn't handle all Jewish holidays or moon phases.
