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] [-U UTC-offset] [-l longitude]

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.

     -l	longitude, -U UTC-offset
	     Only one is needed: Perform lunar and solar calculations from
	     this longitude or from this UTC offset.  If neither is specified,
	     the calculations will be based on the difference between UTC time
	     and localtime.

     -W	num  Print lines from today and	the next num days (forward, future).
	     Ignore weekends when calculating the number of days.

FILE FORMAT
     To	handle calendars in your national code table you can specify
     ``LANG=<locale_name>'' in the calendar file as early as possible.

     To	handle the local name of sequences, you	can specify them as:
     ``SEQUENCE=<first>	<second> <third> <fourth> <fifth> <last>'' in the cal-
     endar file	as early as possible.

     The names of the following	special	days are recognized:
     Easter	      Catholic Easter.
     Paskha	      Orthodox Easter.
     NewMoon	      The lunar	New Moon.
     FullMoon	      The lunar	Full Moon.
     MarEquinox	      The solar	equinox	in March.
     JunSolstice      The solar	solstice in June.
     SepEquinox	      The solar	equinox	in March.
     DecSolstice      The solar	solstice in December.
     ChineseNewYear   The first	day of the Chinese year.
     These names may be	reassigned to their local names	via an assignment like
     ``Easter=Pasen'' in the calendar 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 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.

     The names of the recognized special days may be followed by a positive or
     negative integer, like: ``Easter+3'' or ``Pashka-4''.

     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)

	   LANG=C
	   Easter=Ostern

	   #include <calendar.usholiday>
	   #include <calendar.birthday>

	   Thursday\tEvery Thursday.
	   June\tEvery June 1st.

FILES
     calendar		 file in current directory
     ~/.calendar	 calendar HOME directory.  A chdir is done into	this

     calendar.birthday	   Births and deaths of	famous (and not-so-famous)
			   people.

     calendar.world	   Includes all	calendar files except for national
			   files.

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 recog-
     nized when	it occurs at the beginning of a	line.

SEE ALSO
     at(1), cpp(1), mail(1), cron(8)

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

NOTES
     Chinese New Year is calculated at 120 degrees east	of Greenwich, which
     roughly corresponds with the east coast of	China.	For people west	of
     China, this might result that the start of	Chinese	New Year and the day
     of	the related new	moon might differ.

     The phases	of the moon and	the longitude of the sun are calculated
     against the local position	which corresponds with 30 degrees times	the
     time-difference towards Greenwich.

     The new and full moons are	happening on the day indicated:	They might
     happen in the time	period in the early night or in	the late evening.  It
     doesn't indicate that they	are starting in	the night on that date.

     Because of	minor differences between the output of	the formulas used and
     other sources on the Internet, Druids and Werewolves should double-check
     the start and end time of solar and lunar events.

BUGS
     The calendar utility does not handle Jewish holidays.

     There is no possibility to	properly specify the local position needed for
     solar and lunar calculations.
