     cal -- displays a calendar

     cal [-smjy13] [[month] year]

     Cal displays a simple calendar.  If arguments are not specified, the cur-
     rent month	is displayed.  The options are as follows:

     -1	     Display single month output.  (This is the	default.)

     -3	     Display prev/current/next month output.

     -s	     Display Sunday as the first day of	the week.  (This is the	de-

     -m	     Display Monday as the first day of	the week.

     -j	     Display Julian dates (days	one-based, numbered from January 1).

     -y	     Display a calendar	for the	current	year.

     A single parameter	specifies the year (1 -	9999) to be displayed; note
     the year must be fully specified: "cal 89"	will not display a calendar
     for 1989.	Two parameters denote the month	(1 - 12) and year.  If no pa-
     rameters are specified, the current month's calendar is displayed.

     A year starts on Jan 1.

     The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd
     of	September.  By this time, most countries had recognized	the reforma-
     tion (although a few did not recognize it until the early 1900's.)	 Ten
     days following that date were eliminated by the reformation, so the cal-
     endar for that month is a bit unusual.

     A cal command appeared in Version 6 AT&T UNIX.

     Several much more elaborate versions of this program exist, with support
     for colors, holidays, birthdays, reminders	and appointments, etc. For ex-
     ample, try	the cal	from
     or	GNU gcal.
