calendar − reminder service
calendar [ − ]
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’. 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).

Your calendar
must be public information for you to get reminder service.
Calendar’s extended idea of ’tomorrow’
doesn’t account for holidays.
