CALENDAR(1)		  BSD General Commands Manual		   CALENDAR(1)

NAME
     calendar - reminder service

SYNOPSIS
     calendar [-a] [-A num] [-b] [-B num] [-f calendarfile] [-l num] [-w num]
	      [-t dd[.mm[.year]]]

DESCRIPTION
     The calendar utility checks the current directory or the directory speci
     fied by the CALENDAR_DIR environment variable for a file named calendar
     and displays lines that begin with either todays date or tomorrows.  On
     Fridays, events on Friday through Monday are displayed.

     The options are as follows:

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

     -A num  Print lines from today and next num days. Defaults to one.

     -b      Enforce special date calculation mode for KOI8 calendars.

     -B num  Print lines from today and previous num days. Defaults to zero.

     -f calendarfile
	     Use calendarfile as the default calendar file.

     -l num  Print lines from today and next num days. Defaults to one.

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

     -t dd[.mm[.year]]
	     Act like the specified value is today instead of using the cur
	     rent date.

     To handle calendars in your national code table you can specify
     LANG= in the calendar file as early as possible.  To han
     dle national Easter names in the calendars, Easter= (for
     Catholic Easter) or Paskha= (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 descriptions will
     be encoded in UTF-8.  This is usually used for the distributed calendar
     files.

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

     Note that the locale is reset to the users 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 posi
     tive or negative integer) is Easter for this year.  Paskha (may be fol
     lowed 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  character in the line; if
     the line does not contain a  character, it isnt printed out.	If
     the first character in the line is a  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 /etc/calendar, and
     finally in /usr/share/calendar.  Empty lines and lines protected by the C
     commenting syntax (/* ... */) are ignored.

     Some possible calendar entries ( characters are highlighted by a \t
     sequence):

	   LANG=C
	   Easter=Ostern

	   #include 
	   #include 

	   6/15\tJune 15 (if ambiguous, will default to month/day).
	   Jun. 15\tJune 15.
	   15 June\tJune 15.
	   Thursday\tEvery Thursday.
	   June\tEvery June    1st.
	   15 *\t15th of every month.

	   May Sun+2\tsecond Sunday in May (Muttertag)
	   04/SunLast\tlast    Sunday in April,
	   \tsummer  time in   Europe
	   Easter\tEaster
	   Ostern-2\tGood Friday (2 days before Easter)
	   Paskha\tOrthodox    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 recog
     nized when it occurs at the beginning of a line.

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

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

     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 doesnt handle Jewish holidays or moon phases. The -A and -l
     flags do the same thing.
