CAL(1)                  FreeBSD General Commands Manual                 CAL(1)

NAME
     cal, ncal - displays a calendar and the date of Easter

SYNOPSIS
     cal [-3hjy] [-A number] [-B number] [[month] year]
     cal [-3hj] [-A number] [-B number] -m month [year]
     ncal [-3hjJpwy] [-A number] [-B number] [-s country_code] [[month] year]
     ncal [-3hJeo] [-A number] [-B number] [year]
     ncal [-CN] [-H yyyy-mm-dd] [-d yyyy-mm]

DESCRIPTION
     The cal utility displays a simple calendar in traditional format and ncal
     offers an alternative layout, more options and the date of Easter.  The
     new format is a little cramped but it makes a year fit on a 25x80
     terminal.  If arguments are not specified, the current month is
     displayed.

     The options are as follows:

     -h      Turns off highlighting of today.

     -J      Display Julian Calendar, if combined with the -e option, display
             date of Easter according to the Julian Calendar.

     -e      Display date of Easter (for western churches).

     -j      Display Julian days (days one-based, numbered from January 1).

     -m month
             Display the specified month.  If month is specified as a decimal
             number, it may be followed by the letter `f' or `p' to indicate
             the following or preceding month of that number, respectively.

     -o      Display date of Orthodox Easter (Greek and Russian Orthodox
             Churches).

     -p      Print the country codes and switching days from Julian to
             Gregorian Calendar as they are assumed by ncal.  The country code
             as determined from the local environment is marked with an
             asterisk.

     -s country_code
             Assume the switch from Julian to Gregorian Calendar at the date
             associated with the country_code.  If not specified, ncal tries
             to guess the switch date from the local environment or falls back
             to September 2, 1752.  This was when Great Britain and her
             colonies switched to the Gregorian Calendar.

     -w      Print the number of the week below each week column.

     -y      Display a calendar for the specified year.

     -3      Display the previous, current and next month surrounding today.

     -A number
             Display the number of months after the current month.

     -B number
             Display the number of months before the current month.

     -C      Switch to cal mode.

     -N      Switch to ncal mode.

     -d yyyy-mm
             Use yyyy-mm as the current date (for debugging of date
             selection).

     -H yyyy-mm-dd
             Use yyyy-mm-dd as the current date (for debugging of
             highlighting).

     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 and year; the month is either a
     number between 1 and 12, or a full or abbreviated name as specified by
     the current locale.  Month and year default to those of the current
     system clock and time zone (so "cal -m 8" will display a calendar for the
     month of August in the current year).

     Not all options can be used together.  For example "-3 -A 2 -B 3 -y -m 7"
     would mean: show me the three months around the seventh month, three
     before that, two after that and the whole year.  ncal will warn about
     these combinations.

     A year starts on January 1.

     Highlighting of dates is disabled if stdout is not a tty.

STANDARDS
     The cal utility is compliant with the X/Open System Interfaces option of
     the IEEE Std 1003.1-2008 ("POSIX.1") specification.

     The flags [-3hyJeopw], as well as the ability to specify a month name as
     a single argument, are extensions to that specification.

     The week number computed by -w is compliant with the ISO 8601
     specification.

HISTORY
     A cal command appeared in Version 1 AT&T UNIX.  The ncal command appeared
     in FreeBSD 2.2.6.

AUTHORS
     The ncal command and manual were written by Wolfgang Helbig
     <helbig@FreeBSD.org>.

BUGS
     The assignment of Julian-Gregorian switching dates to country codes is
     historically naive for many countries.

     Not all options are compatible and using them in different orders will
     give varying results.

     It is not possible to display Monday as the first day of the week with
     cal.
