CAL(1) BSD General Commands Manual CAL(1)
NAME
cal - displays a calendar
SYNOPSIS
cal [-smjy13] [[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. (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).
q -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 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.
