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:
-h
Turns off
highlighting of today.
-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).
-m month
Display the specified
month. If month is specified as a decimal
number, it may be followed by the letter ’f’ or
’p’ to indicate the following or preceding month
of that number, respectively.
-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 determined from the local environment is marked with
an asterisk.
-s
country_code
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 specified year. This option is implied when
a year but no month are specified on the command line.
-3
Display the
previous, current and next month surrounding today.
-1
Display only
the current month. This is the default.
-A
number
Months to add after. The
specified number of months is added to the end of the
display. This is in addition to any date range selected by
the -y, -3, or -1
options. For example, ’’cal -y -B2
-A2’’ shows everything from November of the
previous year to February of the following year. Negative
numbers are allowed, in which case the specified number of
months is subtracted. For example, ’’cal -y
-B-6’’ shows July to December. And
’’cal -A11’’ simply shows the next
12 months.
-B
number
Months to add before. The
specified number of months is added to the beginning of the
display. See -A for examples.
-C
Switch to
cal mode.
-N
Switch to
ncal mode.
-d
yyyy-mm
Use yyyy-mm as the
current date (for debugging of date selection).
-H
yyyy-mm-dd
Use yyyy-mm-dd as the
current date (for debugging of highlighting).
-M
Weeks start on
Monday.
-S
Weeks start on
Sunday.
-b
Use oldstyle
format for ncal output.
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. Month and year
default to those of the current system clock and time zone
(so ’’cal -m 8’’ will display a
calendar for the month of August in the current year).
Not all options
can be used together. For example, the options
-y, -3, and -1 are
mutually exclusive. If inconsistent options are given, the
later ones take precedence over the earlier ones.
A year starts on
January 1.
bugs
The assignment of
Julian–Gregorian switching dates to country codes is
historically naive for many countries.
Not all options
are compatible and using them in different orders will give
varying results.

history
A cal command appeared in
Version 5 AT&T UNIX. The ncal command
appeared in FreeBSD 2.2.6. The output of the cal
command is supposed to be bit for bit compatible to the
original Unix cal command, because its output is
processed by other programs like CGI scripts, that should
not be broken. Therefore it will always output 8 lines, even
if only 7 contain data. This extra blank line also appears
with the original cal command, at least on solaris
8
