(If you think
I'm joking, you may search it on Google and see it for yourself.)
In case you
haven't noticed, 11 days are simply missing from the month.
explanation: This was the month during which England shifted from the Roman Julian
Calendar to the Gregorian Calendar.
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. (A King could order
anything, couldn't he?)
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!!!
