Gcal(1) a program for calculating and printing calendars.


gcal [[Option...] [%Date] [@File...]] [Command]


Gcal is a program similar the standard calendar programs BSD-`cal' and `calendar'.

Gcal displays hybrid and proleptic Julian and Gregorian calendar sheets, respectively, for one month, three months or a whole year. It also displays eternal holiday lists for many countries around the globe, and features a very powerful creation of fixed date lists that can be used for reminding purposes. Gcal can calculate various astronomical data and times of the Sun and the Moon for at pleasure any location, precisely enough for most civil purposes. Gcal supports some other calendar systems, for example the Chinese and Japanese calendar, the Hebrew calendar and the civil Islamic calendar, too.

If Gcal is started without any options or commands, a calendar of the current month is displayed.

If the calendar of a definite year is wanted, the year must be fully specified,

e.g.:  gcal 94

displays a year calendar of the year 94, not of the year 1994.

If two arguments are given in the command part, the first argument denotes the month and the second argument denotes the year. In case any illegal commands are given running Gcal , the program will use internal defaults.
