10 | C\bCa\bal\bl displays a simple calendar. If arguments are not specified, the cur- | |
11 | rent month is displayed. The options are as follows: | |
12 | ||
13 | -\b-j\bj Display julian dates (days one-based, numbered from January 1). | |
14 | ||
15 | -\b-y\by Display a calendar for the current year. | |
16 | ||
17 | A single parameter specifies the year (1 - 9999) to be displayed; note | |
18 | the year must be fully specified: ``cal 89'' will _\bn_\bo_\bt display a calendar | |
19 | for 1989. Two parameters denote the month (1 - 12) and year. If no pa- | |
20 | rameters are specified, the current month's calendar is displayed. | |
21 | ||
22 | A year starts on Jan 1. | |

24 | The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd | |
25 | of September. By this time, most countries had recognized the reforma- | |
26 | tion (although a few did not recognize it until the early 1900's.) Ten | |
27 | days following that date were eliminated by the reformation, so the cal- | |
28 | endar for that month is a bit unusual. | |
