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.
16th century The 16th century begins with the Julian year 1501 and ends with either the Julian or the Gregorian year 1600 (depending on the reckoning used; the Gregorian calendar introduced a lapse of 10 days in October 1582).[1]
