46 | The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd |
47 | of September. | |
48 | By this time, most countries had recognized the reformation (although a | |
49 | few did not recognize it until the early 1900's.) | |
50 | Ten days following that date were eliminated by the reformation, so the | |
51 | calendar for that month is a bit unusual. | |
