NAME
       cal - print calendar

SYNOPSIS
       cal [ month ] [ year ]

DESCRIPTION
       Cal  prints  a  calendar.   Month  is either a number from 1 to 12, a lower case month name, or a lower case three-letter prefix of a month
       name.  Year can be between 1 and 9999.  If either month or year is omitted, the current month or year is used.  If  only  one  argument	is
       given, and it is a number larger than 12, a calendar for all twelve months of the given year is produced; otherwise a calendar for just one
       month is printed.  The calendar produced is that for England and her colonies.

       Try
	    cal sep 1752

SOURCE
       /src/cmd/cal.c

BUGS
       The year is always considered to start in January even though this is historically naive.

       Beware that refers to the early Christian era, not the 20th century.
