| .SH DESCRIPTION |
| .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 |
| .I month |
| or |
| .I 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. |
