.I Cal
prints a calendar.
.I 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.
.I Year
can be between 1
and 9999.
If either

or

a calendar for all twelve months of the given year is produced;
otherwise a calendar for just one month is printed. The calendar
produced follows the Calendar (New Style) Act of 1750.
