SYNOPSIS
cal
[-smjy13
]
[[ month ] year
]
DESCRIPTION
Cal
displays a simple calendar.
If arguments are not specified,
the current month is displayed.
The options are as follows:
-1
Display single month output.
(This is the default.)
-3
Display prev/current/next month output.
-s
Display Sunday as the first day of the week.
(This is the default.)
-m
Display Monday as the first day of the week.
-j
Display Julian dates (days one-based, numbered from January 1).
-y
Display a calendar for the current year.
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.
If no parameters are specified, the current month's calendar is
displayed.
A year starts on Jan 1.
The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd
of September.
By this time, most countries had recognized the reformation (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.
OTHER VERSIONS
Several much more elaborate versions of this program exist,
with support for colors, holidays, birthdays, reminders and
appointments, etc. For example, try the cal from
