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