When did daylight saving time begin in the United States? Has there ever been a calendar year from Jan. 1 to Dec. 31 that it ran without stopping?

Congress initiated the first daylight saving time in the United States in 1918, but the law was repealed a year later, though it was voluntarily continued by some states and cities. It was again observed during World War II. In 1966, Congress passed the Uniform Time Act, which created a standard calendar for daylight saving time, setting clocks ahead by one hour. From Jan. 6, 1974, to Oct. 27, 1974, in an attempt to conserve energy, the government extended daylight saving time. Daylight saving was again enacted from Feb. 23, 1975, to Oct. 26, 1975. This year, DST ends Nov. 2.
