|
|

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.
