     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

     -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
     parameters are specified, the current month's calendar is displayed.

     A year starts on Jan 1.

     The Gregorian Reformation is assumed to have occurred in(1,8) 1752 on the 3rd
     of September.  By this time(1,2,n), 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(1,8) 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
     example, try the cal from
     or GNU gcal.
