Have u ever seen the calendar for September 1752??
Isn't the output queer? A month with whole of eleven days missing.
This was the time England shifted from Roman Julian Calendar to the Gregorian Calendar, and the king of England ordered those 11 days to be wiped off the face of the month of September of 1752. (What couldn't a King do in those days?!) And yes, the workers worked for 11 days less, but got paid for the entire 30 days. And that's how "Paid Leave" was born.
At that time, there were two major calendar changes introduced in 1752. First, the church and historical calendars were brought together - both were to run from January 1st to December 31st. Secondly, the Gregorian calendar, which had been in use in Catholic countries since 1582 or shortly thereafter, was adopted in place of the Julian calendar. By 1752 the two calendars differed by 11 days, and the change was accomplished by naming the day after September 2nd, 1752, as September 14th, 1752.
