CAL 1
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 .EX cal sep 1752

The year is always considered to start in January even though this
is historically naive.
Beware that .L "cal 90" refers to the early Christian era, not the 20th century.
