OPTIONS
  None

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.

  year
      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.

  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:

  0   Successful completion.

  >0  An 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.

  TZ  Determines the time zone used to calculate the value of the current
      month.
