OPERANDS

month
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 displays a calendar for the entire year, unless year is also omitted. 

yearNames 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. 

If no operands are specified, cal displays a calendar for the current month. 

DESCRIPTION

The cal command writes to standard output a Gregorian calendar for the specified year or month. 

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. 

EXIT STATUS

The following exit values are returned:

0Successful completion. 

>0An error occurred. 

EXAMPLES

     1.To display a calendar for February 1990, enter:

cal 2 1990

     2.To display a calendar for the year 84 A.D., enter:

cal 84

     3.To display a calendar for the current month, enter:

cal

ENVIRONMENT VARIABLES

The following environment variables affect the execution of ∗cmd∗:

LANG
Provides a default value for the internationalization variables that are unset or null. If LANG is unset or null, the corresponding value from the default locale is used.  If any of the internationalization variables contain an invalid setting, the utility behaves as if none of the variables had been defined. 

LC_ALL
If set to a non-empty string value, overrides the values of all the other internationalization variables.

LC_CTYPE
Determines the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as opposed to multibyte characters in arguments).

LC_MESSAGES
Determines the locale for the format and contents of diagnostic messages written to standard error.

LC_TIME
Determines the format and contents of the calendar.

NLSPATH
Determines the location of message catalogues for the processing of LC_MESSAGES. 

TZDetermines the time zone used to calculate the value of the current month.
