George Washington's Birthday is celebrated as a federal holiday on the third Monday in February. It is one of eleven permanent holidays established by Congress.
Federal holidays apply only to the federal government and the District of Columbia; Congress has never declared a national holiday binding in all states and each state decides its own legal holidays.
George Washington was born in Virginia on February 11, 1731, according to the then-used Julian calendar. In 1752, however, Britain and all its colonies adopted the Gregorian calendar which moved Washington's birthday a year and 11 days to February 22, 1732.
At the recommendation of the Committee, chaired by Henry Clay of the Senate and Philemon Thomas of the House, Congress adjourned on February 22, 1832 out of respect for Washington's memory and in commemoration of his birth.
