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 LCTIME (see environ(5)). (See date(1)
for the allowable list of field descriptors.)
EXAMPLES
The following example shows the possible contents of a template:
%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>
FILES

dates
