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 standard month-day dates, such as ‘Dec. 7,’ ‘december 7,’ ‘12/7,’ etc., are recognized, but not ‘7 December’ or ‘7/12’.  If just a date is entered, (i.e. “1”), that day in any month is acceptable.  On weekends, ‘tomorrow’ extends through Monday. 

When an argument is present, calendar performs its function for every user who has a file ‘calendar’ in his login directory and sends him any positive results by mail(1). Normally, this procedure is performed daily during late hours under control of cron(8).

FILES

/usr/lib/calendar to figure out today’s and tomorrow’s dates

BUGS

Calendar’s extended interpretation of ‘tomorrow’ does not include holidays.
