72 | .Dq Li cal 89 | |
73 | will | |
74 | .Em not | |
75 | display a calendar for 1989. | |

81 | .Pp | |
82 | The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd | |
83 | of September. | |
84 | By this time, most countries had recognized the reformation (although a | |
85 | few did not recognize it until the early 1900's.) | |
86 | Ten days following that date were eliminated by the reformation, so the | |
87 | calendar for that month is a bit unusual. | |
