CAL(1) General Commands Manual CAL(1) NAME cal, ncal -- displays a calendar and the date of easter SYNOPSIS cal [-jy] [[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). -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 deter- mined from the local environment is marked with an asterisk. -s country_code Assume the switch from Julian to Gregorian Calendar at the date as- sociated 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 num- ber between 1 and 12, or a full or abbreviated name as specified by the current locale. A year starts on Jan 1. SEE ALSO calendar(3), strftime(3) HISTORY A cal command appeared in Version 5 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. FreeBSD 5.0 December 16, 1997 CAL(1)
