12 Gcal is a program similar the standard calendar programs BSD-`cal' and
13 `calendar'.
14
15 Gcal displays hybrid and proleptic Julian and Gregorian calendar
16 sheets, respectively, for one month, three months or a whole year. It
17 also displays eternal holiday lists for many countries around the
18 globe, and features a very powerful creation of fixed date lists that
19 can be used for reminding purposes. Gcal can calculate various astro‐
20 nomical data and times of the Sun and the Moon for at pleasure any
21 location, precisely enough for most civil purposes. Gcal supports some
22 other calendar systems, for example the Chinese and Japanese calendar,
23 the Hebrew calendar and the civil Islamic calendar, too.
24
25 If Gcal is started without any options or commands, a calendar of the
26 current month is displayed.
27
28 If the calendar of a definite year is wanted, the year must be fully
29 specified,
30 e.g.: gcal 94
31 displays a year calendar of the year 94, not of the year 1994.
32
33 If two arguments are given in the command part, the first argument
34 denotes the month and the second argument denotes the year. In case any
35 illegal commands are given running Gcal , the program will use internal
36 defaults.
