About the British calendar change of 1752

Under the Calendar (New Style) Act 1750, Great Britain and its colonies, including those in America, made Wednesday 2 September 1752 followed by Thursday 14 September. The act also moved the start of the legal year in England from 25 March to 1 January, so 1751 was a short year. The British tax year still ends on 5 April, reflecting the old Lady Day year end shifted by the lost days and a later adjustment.
