New Style date

The New Style date (NS) is the date of an event, astronomical or historical, according to the Gregorian calendar. This system was adopted by Britain and its American colonies on 14 September 1752, but was introduced at other times elsewhere, with the result that confusion can arise unless the form of calendar being referred to is specified. Dates according to the older Julian calendar are said to be Old Style dates (OS).
