NAME ^

cal - displays a calendar

SYNOPSIS ^

cal [-jy] [[month] year]

DESCRIPTION ^

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

-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.) Eleven days following that date were eliminated by the reformation, so the calendar for that month is a bit unusual.

STANDARDS ^

The cal command offers a superset of IEEE Std1003.2 (``Posix.2'') functionality.

HISTORY ^

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