This idea was first implemented by the French in 1784, after a satirical article by Benjamin Franklin. America first adopted this idea during World War I, and in World War II, it was mandated to occur year-round. President Lyndon Johnson signed the Uniform Time Act of 1966 to make this nationwide,* unless a state opted out. Alaska, Hawaii, and Arizona have never had this, and most of Indiana did not use this until a 2005 state law mandated its use. For 10 points, name this concept, in which Americans move their clocks forward in March and back in November.
