He was born on 4th January 1643 (OS 25th December 1642) Old Style (or OS) and New Style (or NS) are used in English language historical studies either to indicate that the start of the Julian year has been adjusted to start on 1 January (NS) even though contemporary documents use a different start of year (OS); or to indicate that a date conforms to the Julian calendar (OS), formerly in use in many countries, rather than the Gregorian calendar (NS). In Great Britain (except Scotland) and the British colonies the change of start of the year and the change over from the Julian calendar occurred in 1752 and was enabled by the Calendar (New Style) Act 1750.
