print a calendar
cal [ [ month ] year ]
The cal command prints a Gregorian calendar for the
specified year. If a month is also specified, a calendar for that
month only is printed. If no arguments are specified, the current,
previous, and following months are printed, along with the current
date and time. The year must be a number between 1 and
9999; month must be a number between 1 and 12 or enough
characters to specify a particular month. For example, ``May'' must
be given in full to distinguish it from March, but ``S'' is
sufficient to specify September. If only a month string is given,
only that month of the current year is printed.
cal returns the following values:

Note that ``cal 84'' refers to the year 84, not 1984.
The calendar produced is the Gregorian calendar from September 14
1752 onward. Dates up to and including September 2 1752 use the
Julian calendar. (England and her colonies switched from the Julian
to the Gregorian calendar in September 1752, at which time eleven
days were excised from the year. To see the result of this switch,
try cal 9 1752.)
cal is conformant with:
