NAME
       calendar - reminder service

SYNOPSIS
       calendar [-] [-r]

OPTIONS
       -      Work for every user and send mail to him

       -r     Restrict multiple execution on the same day

EXAMPLES
       calendar 	   # Check calendar file in current directory

       calendar 	   # Normary used under the control of cron(8)

       calendar -r	   #  Normary used in /etc/rc file

DESCRIPTION
       Basically  calendar program consults the file calendar in the current directory and display lines which contain today's or tomorrow's date.
       Month-day formats such as '12/25', 'Dec. 25', 'december 25', '*/25', '12/*', '*/*' are recognized.  The asterisk means 'all' days or  'all'
       months.	 On  weekends  'tomorrow' extends through next Monday without any consideration about holidays.  To prevent ambiguity, the formats
       '25 Dec.' and '25/12' are not recognized.

       When an argument - is present, calendar works for all users with a file calendar in their login directories and sends them mail.   Normally
       this is done daily under the control of cron.

       The  -r	option	does  its the same job as - option, but touches the calendar to prevents further access on the same day.  Normally this is
       done in the /etc/rc file on a machine  which may be booted several times in one day.
