when did england switch to the gregorian calendar
Calendar (New Style) Act 1750 In England and Wales, the legal year 1751 was a short year of 282 days, running from 25 March to 31 December. 1752 began on 1 January. To align the calendar in use in England to that on the continent, the Gregorian calendar was adopted: and the calendar was advanced by 11 days: Wednesday 2 September 1752 was followed by Thursday 14 September 1752.[c] The year 1752 was thus a short year (355 days) as well.
Julian calendar Although the new calendar was much simpler than the pre-Julian calendar, the pontifices initially added a leap day every three years, instead of every four. There are accounts of this in Solinus,[40] Pliny,[41] Ammianus,[42] Suetonius,[43] and Censorinus.[44]
