The missing 11 days of september

Have you ever checked the September month of 1752?

Did You Notice: After the 2nd, the calendar skips to the 14th of September !!! 

Wonder Why?

Actually,
The British used to follow the Julian Calendar. The Julian Calendar was based on the solar year with a leap year for every four years. But it had an error rate of 3 extra days for every four centuries.

On the other hand, the Gregorian Calendar doesn't count it as a leap year if the year was directly divisible by 100, except if it was directly divisible by 400. It was more accurate with an error rate of just 1 day for every 3,300 years.

So, Britain decided to abandon the Julian calendar in favour of the gregorian calendar. For this reason, the date after 2nd September had to be shipped directly to 14th September.

Whatever may be the reason, this month stands as the most interesting month in the history of the British calendar for me ;)
