The missing of the 11 days in the world calendar in September 1752, happened when Pope Gregory XIII ordered that a change in the Julian to the Gregorian calendar in 1582, which lead to the reduction of eleven (11) days from the calendar.
The 11 days was cut between 2nd September and 14th September, 1752. Despite the reduction in the days of the month, the government then paid its worker full payment (i.e 30 days working).
In 325 A.D Nicene council adopted the Julian calendar declaring that a year would be 365 days and 6 hours long and 25th march be the New Year. Astronomers found out many centuries passed the error in Julian calendar exceeded the newly method of measurement “the Solar year by 11 minutes. Resulting to over time from 325 A.D to 1582 A.D, excess of nearly 10days
In order to make up with the excessive day from 325AD t0 1582AD and for the days to go in uniform, Pope Gregory XIII ordered a new calendar which is named GREOGRIAN CALENDAR , as Julian calendar did not have a leap years, the difference of 11 days had be cut down.
On 1752, the government declared a cut down in the dates between 2nd and 14th of September for every colonies that they are in control off. This means that the British, Isles, English and America colonies lost 11days in the month of September 1752. September 1752 started with 1, 2 but skipped 3rd to 13th and then continued with 14th till 30th of the month, meaning that from 3rd to 13th September, 1752 never really existed, which erupted several riots from workers as they fear that no payment of salaries will be paid for the missing 11 days of the month.
To let peace take it’s appropriate place the government paid up the bill for the full 30 days, while the workers worked for only 19 days in 1752 September.
The British, as a matter of fact were among the last nations in the world to make the days disappear. The numbers had already been vanished in many places – France in 1582, Norway in 1700 and so on.
