Mystery Missing Dates

Did you know the days/dates between 2nd and 14th September in 1752 did NOT exist? This is because this was the year that the calendar changed from the Julian (Julius Caesar) to the Gregorian (Pope Gregory XIII) calendar and because the Julian calendar did not have leap years, they had to cut out dates to make the years correct for the new calendar. So the days went 1, 2, 14, 15, 16....30. But the month still ended with 30 so people worked for 11 days less but got paid for 30 days. This is how paid leave started. England was the last country to adopt this system.
