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

       /sys/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.

NAME

       cal - display a calendar

SYNOPSIS

       cal [options] [[[day] month] year]

DESCRIPTION

       cal displays a simple calendar.	If no arguments are specified, the current month is displayed.

       -h, --help
	      Display help screen and exit.

PARAMETERS

       A single parameter specifies the year (1 - 9999) to be displayed; note the year must be fully specified: cal 89 will not display a calendar
       for 1989.

       Two parameters denote the month (1 - 12) and year.

       Three parameters denote the day (1-31), month and year, and the day will be highlighted if the calendar is displayed on a terminal.  If	no
       parameters are specified, the current month's calendar is displayed.

       A year starts on Jan 1. The first day of the week is determined by the locale.

       The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd of September. By this time, most countries had recognized the ref-
       ormation (although a few did not recognize it until the early 1900's). Ten days following that date were eliminated by the reformation,	so
       the calendar for that month is a bit unusual.

HISTORY

       A cal command appeared in Version 6 AT&T UNIX.
