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