CAL(1) BSD General Commands Manual CAL(1)
NAME
cal — displays a calendar
SYNOPSIS
cal [−mjy13] [[month] year]
DESCRIPTION
Cal displays a simple calendar. If arguments are not specified, the current month is displayed. The options are as follows:
−1
Display single month output (use if cal was built with -3 as default to get older traditional output)
−3
Display prev/current/next month output (use if cal was built with traditional -1 as default to get newer improved output)
−m
Display Monday as the first day of the week. (The default is Sunday.)
−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.
