The Uniform Monday Holiday Act (Pub.L. 90–363, 82 Stat. 250, enacted June 28, 1968) is an Act of Congress that moved permanently to a Monday three Federal holidays in the United States—Washington's Birthday (colloquially Presidents’ Day), Memorial Day, and Labor 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 and Labor Day Weekend. The Act was signed into law on June 1, 1968, and took effect on January 1, 1971.
