NAME
cal - print calendar
SYNOPSIS
cal [[month ] year ]
DESCRIPTION
cal prints a calendar for the specified year. If a month is also specified, a calendar just for that month is
printed. If neither is specified, a calendar for the present month is printed. year can be between 1 and
9999. month is a decimal number between 1 and 12. The calendar produced is a Gregorian calendar.
EXTERNAL INFLUENCES
For information about the UNIX Standard environment, see standards (5).
Environment Variables
LANG determines the locale to use for the locale categories when both
LC_ALL and the corresponding
environment variable (beginning with
LC_) do not specify a locale. If
LANG is not set or is set to the
empty string, a default of "C" (see lang(5)) is used.
LC_CTYPE determines the locale for interpretation of sequences of bytes of text data as characters (e.g.,
single- verses multibyte characters in arguments and input files).
LC_TIME determines the format and contents of the calendar.
TZ determines the timezone used to calculate the value of the current month.
If any internationalization variable contains an invalid setting,
cal behaves as if all internationalization
variables are set to "C". See environ (5).
International Code Set Support
Single- and multi-byte character code sets are supported.
EXAMPLES
The command:
cal 9 1850
prints the calendar for September, 1850 on the screen as follows:
September 1850
SMTuWThFS
1234567
8 9 10 11 12 13 14
15 16 17 18 19 20 21
22 23 24 25 26 27 28
29 30
However, for UNIX Standard (see standards (5)), the output looks like below:
Sep 1850
Sun Mon Tue Wed Thu Fri Sat
1234567
8 9 10 11 12 13 14
15 16 17 18 19 20 21
22 23 24 25 26 27 28
29 30
WARNINGS
The year is always considered to start in January even though this is historically naive.
Beware that
cal 83 refers to the early Christian era, not the 20th century.
