NAME
     ccaalleennddaarr - reminder service

SYNOPSIS
     ccaalleennddaarr [-aa] [-AA num] [-BB num] [-FF friday] [-ff calendarfile]
              [-tt dd[.mm[.year]]] [-WW num]

DESCRIPTION
     The ccaalleennddaarr 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:

     -AA num  Print lines from today and the next num days (forward, future).

     -aa      Process the ``calendar'' files of all users and mail the results
             to them.  This requires super-user privileges.

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

     -FF friday
             Specify which day of the week is ``Friday'' (the day before the
             weekend begins).  Default is 5.

     -ff calendarfile
             Use calendarfile as the default calendar file.

     -tt dd[.mm[.year]]
             For test purposes only: set date directly to argument values.

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

     -ll days
             Causes the program to ``look ahead'' a given number of days
             (default one) from the specified date and display their entries
             as well.

     -ww days
             Causes the program to add the specified number of days to the
             ``look ahead'' number if and only if the day specified is a Fri-
             day. The default value is two, which causes ccaalleennddaarr to print
             entries through the weekend on Fridays.

     -dd MMDD[[YY]YY]
             Display lines for the given date. By default, the current date is
             used.  The year, which may be given in either two or four digit
             format, is used only for purposes of determining wether the given
             date falls on a Friday in that year (see below). If the year is
             not specified, the current year is assumed.

     To handle calendars in your national code table you can specify
     ``LANG='' in the calendar file as early as possible.  To
     handle national Easter names in the calendars ``Easter=''
     (for Catholic Easter) or ``Paskha='' (for Orthodox Easter)
     can be used.

     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.

     ``Easter'', is Easter for this year, and may be followed by a positive or
     negative integer.

     ``Paskha'', is Orthodox Easter for this year, and may be followed by a
     positive or negative integer.

     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  character in the line; if
     the line does not contain a  character, it is not displayed.  If the
     first character in the line is a  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.

     sequence)

CCOOMMPPAATTIIBBIILLIITTYY
     The ccaalleennddaarr 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.

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

BUGS
     The ccaalleennddaarr utility doesn't handle Jewish holidays and moon phases.
