The Selective Training and Service Act of 1940, also known as the Burke–Wadsworth Act, Pub.L. 76–783, 54 Stat. 885, enacted September 16, 1940, was the first peacetime conscription in United States history. This Selective Service Act required that men who had reached their 21st birthday but had not yet reached their 36th birthday register with local draft boards. Later, when the U.S. entered World War II, all men from their 18th birthday until the day before their 45th birthday were made subject to military service, and all men from their 18th birthday until the day before their 65th birthday were required to register.
