CALENDAR(1)                  BSD Reference Manual                  CALENDAR(1)

NAME

     calendar - reminder service

SYNOPSIS

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

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 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).

     -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.

     -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.

     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.

     Other lines should begin with a month and day. They may be entered in al-
     most any format, either numeric or as character strings. If proper locale
     is set, national months and weekdays names can be used. On OpenBSD and
     MirOS, support for locales is non-existent. 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 nega-
     tive 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 /usr/share/calendar.
     Empty lines and lines protected by the C commenting syntax (/* ... */)
     are ignored.

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

           LANG=C
           Easter=Ostern

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

           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 recognized
     when it occurs at the beginning of a line.

HISTORY

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

     Since MirOS #10, if the UNICODE variable is set during compilation,
     iconv(3) is used to convert any input to OPTU-8 output.

BUGS

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