.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility displays a simple calendar in traditional format and
|
|
.Nm 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.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width indent
|
|
.It Fl J
|
|
Display Julian Calendar, if combined with the
|
|
.Fl e
|
|
option, display date of Easter according to the Julian Calendar.
|
|
.It Fl e
|
|
Display date of Easter (for western churches).
|
|
.It Fl j
|
|
Display Julian days (days one-based, numbered from January 1).
|
|
.It Fl m Ar month
|
|
Display the specified
|
|
.Ar month .
|
|
If
|
|
.Ar month
|
|
is specified as a decimal number, it may be followed by the letter
|
|
.Ql f
|
|
or
|
|
.Ql p
|
|
to indicate the following or preceding month of that number,
|
|
respectively.
|
|
.It Fl o
|
|
Display date of Orthodox Easter (Greek and Russian
|
|
Orthodox Churches).
|
|
.It Fl p
|
|
Print the country codes and switching days from Julian to Gregorian
|
|
Calendar as they are assumed by
|
|
.Nm ncal .
|
|
The country code as determined from the local environment is marked
|
|
with an asterisk.
|
|
.It Fl s Ar country_code
|
|
Assume the switch from Julian to Gregorian Calendar at the date
|
|
associated with the
|
|
.Ar country_code .
|
|
If not specified,
|
|
.Nm 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.
|
|
.It Fl w
|
|
Print the number of the week below each week column.
|
|
.It Fl y
|
|
Display a calendar for the specified year.
|
|
.El
|
|
.Pp
|
|
A single parameter specifies the year (1\(en9999) to be displayed;
|
|
note the year must be fully specified:
|
|
.Dq Li cal 89
|
|
will
|
|
.Em 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
|
|
.Dq Li cal -m 8
|
|
will display a calendar for the month of August in the current year).
|
|
.Pp
|
|
A year starts on January 1.

|
The assignment of Julian\(enGregorian switching dates to
|
|
country codes is historically naive for many countries.
