The origin of the calendar
In the Roman Julian Calendar, April used to be the first month of the year; but the Gregorian Calendar observed January as the first month. Even after shifting to the Gregorian Calendar, many people refused to give up old traditions and continued celebrating 1st April as the New Year's Day. When simple orders didn't work, the King finally issued a royal dictum; which stated that those who celebrated 1st April as the new year's day would be labelled as fools. From then on, 1st April became April Fool's Day.
A Julian year was 11 days longer than a Gregorian year. So, the King of England ordered 11 days to be wiped off the face of that particular month.
So, the workers worked for 11 days less that month, but got paid for the whole month. That's how the concept of "paid leave" was born. Hail the King!!!
