    NAME

    
    
    calendar
    
     - reminder service
    
     
    

    SYNOPSIS

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

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

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

    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.  

    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 AT&T System v7 .  

    BUGS

    calendar doesn't handle Jewish holidays or moon phases. The -A and -l flags do the same thing.
