OPERANDS

       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.  Names the year for which you want  the  calen-
       dar.  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: Successful completion.  An error occurred.

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 To display a  calendar
       for the current month, enter: cal

ENVIRONMENT VARIABLES

       The following environment variables affect the execution of *cmd*: 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 vari-
       ables  contain  an  invalid setting, the utility behaves as if none of the variables had been defined.  If set to a non-empty string value,
       overrides the values of all the other internationalization variables.  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).	Determines the locale for the for-
       mat and contents of diagnostic messages written to standard error.  Determines the format and contents of  the  calendar.   Determines  the
       location  of  message  catalogues  for  the processing of LC_MESSAGES.  Determines the time zone used to calculate the value of the current
       month.
