| .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. | |
