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. The month is a number between 1 and 12. The year can be between 1 and 9999. The calendar produced is in the form of a Gregorian calendar (as used in Western Europe and the United States), but the month and the abbreviated day names are taken from the locale given by the environment variable LC_TIME.

cal examines the environment variables LC_TIME to determine the names of the months and days, and LC_CTYPE for how to print the characters the names are composed from. If the abbreviated day name in the locale entry is longer than two screen columns in width, it is truncated to two columns.

Files

/usr/lib/locale/locale/LC_MESSAGES/uxue: language-specific message file (see LANG on environ(5)).

Notices

An unusual calendar is printed for September 1752. That is the month 11 days were skipped to make up for lack of leap year adjustments. To see this calendar, type:

cal 9 1752

The command cal 83 refers to the year 83, not 1983.

The year is always considered to start in January even though this is historically naive.
