NAME
???? cal - displays a calendar

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

DESCRIPTION
???? 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.

???? -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.

???? -V?? ????? Display version information and exit.

???? 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.? Three
???? parameters denote the day (1-31), month and year, and the day will be
???? highlighted if the calendar is displayed on a terminal.? If no parameters
???? are specified, the current month’s calendar is displayed.

???? A year starts on Jan 1. The first day of the week is determined by the
???? locale.

???? The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd
???? of September.? By this time, 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.

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.

AVAILABILITY
???? The cal command is part of the util-linux-ng package and is available
???? from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
