1500 s dating
To reduce misunderstandings about the date, it was normal in parish registers to place a new year heading after 24 March (for example "1661") and another heading at the end of the following December, "1661/62", a form of dual dating to indicate that in the following few weeks the year was 1661 Old Style but 1662 New Style.Some more modern sources, often more academic ones, also use the "1661/62" style for the period between 1 January and 25 March for years before the introduction of the Gregorian calendar in England. Great Britain, Ireland and the British Empire (including much of what is now the eastern part of the United States) adopted the Gregorian calendar in 1752, by which time it was necessary to correct by 11 days.In Russia, new style dates came into use in early 1918.Other countries in Eastern Orthodoxy adopted new style dating for their civil calendars but most continue to use the Julian calendar for religious use. designation is particularly relevant for dates which fall between the start of the "historical year" (1 January) and the official start date, where different.In English-language histories of other countries (especially Russia), the Anglophone OS/NS convention is often used to identify which calendar is being used when giving a date. But the start of the Julian year was not always 1 January, and was altered at different times in different countries (see New Year's Day in the Julian calendar). This was 25 March in England, Wales and the colonies until 1752.From 1155 to 1752, the civil or legal year in England began on 25 March (Lady Day) The corresponding date in the Gregorian calendar is 9 February 1649, the date by which his contemporaries in some parts of continental Europe would have recorded his execution. During the years between the first introduction of the Gregorian calendar in continental Europe and its introduction in Britain, contemporary usage in England started to change.For example, the Battle of Agincourt is well known to have been fought on 25 October 1415, which is Saint Crispin's Day.But for the period between the first introduction of the Gregorian calendar on 15 October 1582 and its introduction in Britain on 14 September 1752, there can be considerable confusion between events in continental western Europe and in British domains.
For example, the Battle of Blenheim is always given as 13 August 1704.
In the case of Eastern Europe, for example, all of these assumptions would be incorrect.
Usually, the mapping of new dates onto old dates with a start of year adjustment works well with little confusion for events which happened before the introduction of the Gregorian calendar.
Wednesday, 2 September 1752, was followed by Thursday, 14 September 1752.
Claims that rioters demanded "Give us our eleven days" grew out of a misinterpretation of a painting by William Hogarth.
