NAME
     cal -- displays a calendar

SYNOPSIS
     cal [-smjy13] [[month] year]

DESCRIPTION
     Cal displays a simple calendar.  If arguments are not specified, the current month is displayed.  The options are as fol-
     lows:

     -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 default.)

     -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 1752 on the 3rd of September.  By this time, most countries had
     recognized the reformation (although a few did not recognize it until the early 1900's.)  Ten days following that date
     were eliminated by the reformation, so the calendar for that month is a bit unusual.

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

OTHER VERSIONS
     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 http://home.sprynet.com/~cbagwell/projects.html or GNU gcal.
