1.5 deraadt 84: The Gregorian Reformation is assumed to have occurred in 1752 after the 2nd
1.1 deraadt 85: of September.
86: By this time, most countries had recognized the reformation (although a
1.10 aaron 87: few did not recognize it until the early 1900's).
1.5 deraadt 88: Eleven days following that date were eliminated by the reformation, so the
1.1 deraadt 89: calendar for that month is a bit unusual.
