Have u ever seen the calendar for September 1752???
If you are working in Unix, try this out.
At $ prompt, type: cal 9 1752
not only in unix, u can also search it in google
See the explanation for what you see.
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.Hail the King!!!
