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.
World Book Day (UK and Ireland) The Day was first celebrated in 1995 in the United Kingdom. The original, global World Book Day event is generally observed on 23 April - it was changed in the UK to avoid clashes with Easter school holidays and with St George's Day. Conversely, a separate event World Book Night organized by independent charity The Reading Agency is held on 23 April.
