When was George Washington born
From Wikipedia::
The birth and death of George Washington are given using the Gregorian calendar. However, he was born when Britain and her colonies still used the Julian calendar, so contemporary records record his birth as February 11, 1732. The provisions of the Calendar (New Style) Act 1750, implemented in 1752, altered the official British dating method to the Gregorian calendar with the start of the year on January 1.
