The Gregorian Reformation is assumed to have occured 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.
