Congress passed the first DST law in 1918 and repealed it the next year. Franklin Delano Roosevelt imposed year-round DST for three years during the Second World War. In 1966, Congress approved a uniform DST standard for the whole country. In the 1970s, Richard Nixon had the nation go on DST for 15 consecutive months in order to conserve energy. The last president to modify DST was Ronald Reagan, who advanced DST's start date to the first Sunday in April.
