cal(1) — Commands
NAME
cal − Displays a calendar
SYNOPSIS
cal [ [month] year ]
DESCRIPTION
The cal command writes to standard output a Gregorian calendar for the specified year or month.
The month argument names the month for which you want the calendar. It can be a number between 1 and 12 for January through December, respectively. If month is not specified, cal uses the current month.
The year argument names the year for which you want the calendar. Because cal can display a calendar for any year from 1 to 9999, enter the full year rather than just the last two digits. If year is not specified, cal uses the current year.
For historical reasons, the cal command’s Gregorian calendar is discontinuous. The display for September 1752 (cal 9 1752) jumps from Wednesday the 2nd to Thursday the 14th.
The cal command checks the LC_TIME environment variable and uses the correct headers for the current locale. If LC_TIME is not set, cal checks the value of LANG. If neither variable is set, you receive English headers. The appropriate files are in /usr/lib/nls/loc.
EXAMPLES
To display a calendar for February 1990, enter:
cal 2 1990
To display a calendar for the year 84 A.D., enter:
cal 84
