NAME

       cal - print a calendar

SYNOPSIS

       cal [[month] year ]

DESCRIPTION

       The  cal  utility shall write a calendar to standard output using the Julian calendar for dates from January 1, 1 through September 2, 1752
       and the Gregorian calendar for dates from September 14, 1752 through December 31, 9999 as though the Gregorian calendar had been adopted on
       September 14, 1752.

OPTIONS

       None.

OPERANDS

       The following operands shall be supported:

       month  Specify the month to be displayed, represented as a decimal integer from 1 (January) to 12 (December). The default shall be the cur-
	      rent month.

       year   Specify the year for which the calendar is displayed, represented as a decimal integer from 1 to 9999. The default shall be the cur-
	      rent year.

STDIN

       Not used.

INPUT FILES

       None.

ENVIRONMENT VARIABLES

       The following environment variables shall affect the execution of cal:

       LANG   Provide  a  default  value  for  the  internationalization  variables  that  are	unset or null. (See the Base Definitions volume of
	      IEEE Std 1003.1-2001, Section 8.2, Internationalization Variables for the  precedence  of  internationalization  variables  used	to
	      determine the values of locale categories.)

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

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

       LC_MESSAGES
	      Determine the locale that should be used to affect the format and contents of diagnostic messages written  to  standard  error,  and
	      informative messages written to standard output.

       LC_TIME
	      Determine the format and contents of the calendar.

       NLSPATH
	      Determine the location of message catalogs for the processing of LC_MESSAGES .

       TZ     Determine the timezone used to calculate the value of the current month.

ASYNCHRONOUS EVENTS

       Default.

STDOUT

       The standard output shall be used to display the calendar, in an unspecified format.

STDERR

       The standard error shall be used only for diagnostic messages.

OUTPUT FILES

       None.

EXTENDED DESCRIPTION

       None.

EXIT STATUS

CONSEQUENCES OF ERRORS

       Default.

       The following sections are informative.

APPLICATION USAGE

       Note that:

	      cal 83

       refers to A.D. 83, not 1983.

EXAMPLES

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       A future version of IEEE Std 1003.1-2001 may support locale-specific recognition of the date of adoption of the Gregorian calendar.

SEE ALSO

       None.
