CALENDAR(1)
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 ‘Dec. 7,’ ‘december 7,’ ‘12/7,’ etc., are recognized, but not ‘7 December’ or ‘7/12’. If you give just a date, i.e. “1”, that day in any month will do. 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).

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