cal

CAL(1)							    BSD General Commands Manual 						    CAL(1)

NAME

     cal -- displays a calendar

SYNOPSIS

     cal [-smjy13] [[[day] 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.  (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 calen-
     dar 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 ref-
     ormation (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.

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/.
