The Changes of 1752
In accordance with a 1750 act of Parliament, England and its
colonies changed calendars in 1752. By that time, the discrepancy
between a solar year and the Julian Calendar had grown by an
additional day, so that the calendar used in England and its
colonies was 11 days out-of-sync with the Gregorian Calendar in use
in most other parts of Europe.
England's calendar change included three major components. The
Julian Calendar was replaced by the Gregorian Calendar, changing the
formula for calculating leap years. The beginning of the legal new
year was moved from March 25 to January 1. Finally, 11 days were
dropped from the month of September 1752.
The changeover involved a series of steps:
December 31, 1750 was followed by January 1, 1750 (under the "Old
Style" calendar, December was the 10th month and January the 11th)
March 24, 1750 was followed by March 25, 1751 (March 25 was the
first day of the "Old Style" year)
December 31, 1751 was followed by January 1, 1752 (the switch from
March 25 to January 1 as the first day of the year)
September 2, 1752 was followed by September 14, 1752 (drop of 11
days to conform to the Gregorian calendar)
You forgot step 4 which were the riots when the landlords charged a
full 3 month rent for the July-September 1752 quarter instead of
giving a rebate for the non-existent 11 days in the quarter.
