cal, ncal -- displays a calendar and the date of easter
cal [-jy] [[month] year]
ncal [-jJpwy] [-s country_code] [[month] year]
ncal [-Jeo] [year]
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).
-o Display date of orthodox easter (Greek and Russian Orthodox
-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.
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 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 and year; the month is either
a number between 1 and 12, or a full or abbreviated name as specified by
the current locale.
A year starts on Jan 1.
A cal command appeared in Version 5 AT&T UNIX. The ncal command appeared
in FreeBSD 2.2.6.
The ncal command and manual were written by Wolfgang Helbig
The assignment of Julian - Gregorian switching dates to country codes is
historically naive for many countries.
