Presidents' Day, officially Washington's Birthday at the federal governmental level, is a holiday in the United States celebrated on the third Monday of February. It is often celebrated to honor all those who served as presidents of the United States and, since 1879, has been the federal holiday honoring Founding Father George Washington, who led the Continental Army to victory in the American Revolutionary War, presided at the Constitutional Convention of 1787, and was the first U.S. president.

The Uniform Monday Holiday Act is an Act of Congress that moved permanently to a Monday two federal holidays in the United States — Washington's Birthday and Memorial Day — and that made Columbus Day a federal holiday, also permanently on a Monday. This created long weekends with three days off ending with the holidays, such as Memorial Day Weekend.
