Uniform Monday Holiday Act
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.
