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

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

SYNOPSIS
     cal [-jy] [[month] year]
     cal [-j] -m month [year]
     ncal [-jJpwy] [-s country_code] [[month] year]
     ncal [-Jeo] [year]

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:

     -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.

     -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.

     A single parameter specifies the year (1 - 9999) to be displayed; note the year must be fully speci-fied: specified:
     fied: ``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).

     A year starts on Jan 1.

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