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/libexec/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.
