I seem to remember that the calendar jumped 13 days when most European countries switched to the Gregorian calendar in the 18th century. Now, almost three centuries on, the Gregorian and Julian calendars would be even more out of sync, wouldn't they? In three centuries, there would have been about 75 leap days, so, wouldn't the calendars be 88 days out of sync?
If my calculations are correct, that makes tomorrow the Fourth of July!
But, since the Gregorian calendar includes leap years, but the Julian calendar does not, every four years, the two calendars become one more day out of sync. So, in most centuries, there are 24 leap days, meaning that, every 100 years, the discrepancy will increase by 24 days. Every fourth century, there are 25 leap days.
So, to my way of thinking, in 300+ years, the calendars would drift about 75 days.
