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 Aug. 24, august 24, 8/24, etc., are recognized, but not 24 August or 24/8. On weekends ``tomorrow'' extends through Monday. calendar can be invoked regularly by using the crontab(1) or at(1) commands.

When an argument is present, calendar does its job for every user who has a file calendar in his or her login directory and sends them any positive results by mail(1). Normally this is done daily by facilities in the UNIX operating system (see cron(1M)). If the environment variable DATEMSK is set, calendar will use its value as the full path name of a template file containing format strings. The strings consist of field descriptors and text characters and are used to provide a richer set of allowable date formats in different languages by appropriate settings of the environment variable LANG or LC_TIME (see environ(5)). (See date(1) for the allowable list of field descriptors.)

EXAMPLES

The following example shows the possible contents of a  tem-
plate:
     %B %eth of the year %Y
%B represents the full month name, %e the day of  month  and
%Y the year (4 digits).  If DATEMSK is set to this template,
the following calendar file would be valid:
     March 7th of the year 1989 < Reminder>
