CALENDAR(1)                                                        CALENDAR(1)


NAME
       calendar - reminder service

SYNOPSIS
       calendar [ - ]

DESCRIPTION
       Calendar  consults  the  file  ‘calendar’  in the current directory and
       prints out lines that contain today’s or tomorrow’s  date  anywhere  in
       the  line.  Most reasonable month-day dates such as ‘Dec. 7,’ ‘december
       7,’ ‘12/7,’ etc., are recognized, but not ‘7 December’ or  ‘7/12’.   If
       you  give the month as ‘‘*’’ with a date, i.e. ‘‘* 1’’, that day in any
       month will do.  On weekends ‘tomorrow’ extends through Monday.

       When an argument is present, calendar does its job for every  user  who
       has a file ‘calendar’ in his login directory and sends him any positive
       results by mail(1).  Normally this is done daily in the wee hours under
       control of cron(8).

       The  file  ‘calendar’  is  first  run  through  the ‘‘C’’ preprocessor,
       /lib/cpp, to include any other calendar files specified with the  usual
       ‘‘#include’’  syntax.  Included calendars will usually be shared by all
       users, maintained and documented by the local administration.

FILES
       calendar
       /usr/lib/calendar to figure out today’s and tomorrow’s dates
       /etc/passwd
       /tmp/cal*
       /lib/cpp, egrep, sed, mail as subprocesses

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

BUGS
       Calendar’s extended idea of ‘tomorrow’ doesn’t account for holidays.
