NAME

       calendar - reminder service

SYNOPSIS

       calendar [-]

DESCRIPTION

       The  calendar utility consults the file calendar in the current directory and writes lines that contain today's or tomorrow's date anywhere
       in the line to standard output. Most reasonable month-day dates such as Aug. 24, august 24, 8/24, and so forth, are recognized, but not	24
       August  or  24/8.  On  Fridays and weekends "tomorrow" extends through Monday. calendar can be invoked regularly by using the crontab(1) or
       at(1) commands.

       When the optional 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 (seecron(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 conversion specifications and text characters and are used to provide a richer set of allowable date formats in dif-
       ferent  languages  by  appropriate  settings  of  the environment variable LANG or LC_TIME; see environ(5). Seestrftime(3C) for the list of
       allowable conversion specifications.

EXAMPLES

       Example 1: Possible contents of a template

       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>

NOTES

       Appropriate lines beginning with white space will not be printed.

       Your calendar must be public information for you to get reminder service.

       calendar's extended idea of ``tomorrow'' does not account for holidays.

       The  -  argument  works	only  on calendar files that are local to the machine; calendar is intended not to work on calendar files that are
       mounted remotely with NFS. Thus, `calendar -' should be run only on diskful machines where home directories exist;  running it on  a  disk-
       less client has no effect.

       calendar  is no longer in the default root crontab. Because of the network burden `calendar -' can induce, it is inadvisable in an environ-
       ment running ypbind(1M) with a large passwd.byname map.	If, however, the usefulness of calendar outweighs the network impact,  the  super-
       user  may run `crontab -e' to edit the root crontab. Otherwise, individual users may wish to use `crontab -e' to edit their own crontabs to
       have cron invoke calendar without the - argument, piping output to mail addressed to themselves.
