     CCaalleennddaarr checks the current directory for a file named _c_a_l_e_n_d_a_r and dis-
     plays lines that begin with either today's date or tomorrow's.  On Fri-
     days, events on Friday through Monday are displayed.

     The following options are available:

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

     Lines should begin with a month and day.  They may be entered in almost
     any format, either numeric or as character strings.  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 specifica-
     tions for a single date.  By convention, dates followed by an asterisk
     are not fixed, i.e., change from year to year.

     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 _/_u_s_r_/_s_h_a_r_e_/_c_a_l_e_n_d_a_r.
     Empty lines and lines protected by the C commenting syntax (/* ... */)
     are ignored.

     Some possible calendar entries:

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

           6/15      ... June 15 (if ambiguous, will default to month/day).
           Jun. 15        ... June 15.
           15 June        ... June 15.
           Thursday  ... Every Thursday.
           June      ... Every June 1st.
           15 *      ... 15th of every month.

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 first on the line.

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

BBUUGGSS
     CCaalleennddaarr doesn't handle events that move around from year to year, i.e.,
     ``the last Monday in April''.
