CAL(1) FreeBSD General Commands Manual CAL(1) NAME cal - displays a calendar SYNOPSIS cal [-jmwy] [month] [year] DESCRIPTION cal displays a simple calendar. Calendars may be displayed by month or by year. The options are as follows: -j Display Julian dates (days one-based, numbered from January 1). The options -j and -w are mutually exclusive. -m Display weeks starting on Monday instead of Sunday. -w Display week numbers in the month display. If -m is specified, the ISO week format is assumed. The options -j and -w are mutually exclusive. -y Display a calendar for the current year. A single numerical parameter specifies the year (1 - 9999) to be displayed. The year must be fully specified: "cal 89" will not display a calendar for 1989. Two parameters denote the month (1 - 12, or a month name or abbreviation thereof) and year. Alternatively, a single parameter may be given specifying the name or abbreviated name of a month: in that case a calendar is displayed for that month of the current year. If no parameters are specified, the current month's calendar is displayed. A year starts on January 1st. The Gregorian Reformation is assumed to have occurred in 1752 after the 2nd of September. By this time, most countries had recognized the Reformation (although a few did not recognize it until the early 1900s). Eleven days following that date were eliminated by the Reformation, so the calendar for that month is a bit unusual. EXIT STATUS The cal utility exits 0 on success, and >0 if an error occurs. SEE ALSO calendar(1) STANDARDS The cal utility is compliant with the X/Open System Interfaces option of the specification. The flags [-jmwy], as well as the ability to specify a month name as a single argument, are extensions to that specification. The week number computed by -mw is compliant with the ISO 8601 specification. HISTORY A cal command appeared in Version 1 AT&T UNIX. FreeBSD 14.1-RELEASE-p8 July 31, 2024 FreeBSD 14.1-RELEASE-p8
