title: Daylight saving time in the United States text: effort to conserve fuel, Germany began observing DST on May 1, 1916. The rest of Europe soon followed. The plan was not adopted in the United States until the Standard Time Act of March 19, 1918, which confirmed the existing standard time zone system and set summer DST to begin on March 31, 1918 (reverting October 27). The idea was unpopular and Congress abolished DST after the war, overriding President Woodrow Wilson's veto. DST became a local option and was observed in some states until World War II, when President Franklin Roosevelt instituted year-round DST, called "War Time", on February title: Daylight saving time in the United States text: Virgin Islands. During the 1973 oil embargo by the Organization of Arab Petroleum Exporting Countries (OAPEC), in an effort to conserve fuel, Congress enacted a trial period of year-round DST (P.L. 93-182), beginning January 6, 1974, and ending April 27, 1975. The trial was hotly debated. Those in favor pointed to increased daylight hours in the summer evening: more time for recreation, reduced lighting and heating demands, reduced crime, and reduced automobile accidents. The opposition was concerned about children leaving for school in the dark. The act was amended in October 1974 (P.L. 93-434) to return to standard time for title: Daylight saving time text: to conserve coal during wartime. Britain, most of its allies, and many European neutrals soon followed. Russia and a few other countries waited until the next year, and the United States adopted daylight saving in 1918. Broadly speaking, most jurisdictions abandoned daylight saving time in the years after the war ended in 1918 (with some notable exceptions including Canada, the UK, France, Ireland, and the United States). However, many different places adopted it for periods of time during the following decades and it became common during World War II. It became widely adopted, particularly in North America and Europe, starting title: History of time in the United States text: zones was not established in U.S. law until the Standard Time Act of 1918 of March 19, 1918, also known as the Calder Act (15 USC 260). The act also established daylight saving time, itself a contentious idea. Daylight saving time was repealed in 1919, but standard time in time zones remained in law, with the Interstate Commerce Commission (ICC) having the authority over time zone boundaries. Daylight time became a local matter. It was re-established nationally early in World War II, and was continuously observed until the end of the war. After the war its use varied among states title: Daylight saving time in the United States text: no significant difference was found in fatalities among school-age children in the mornings. In 1986 Congress enacted P.L. 99-359, amending the Uniform Time Act by changing the beginning of DST to the first Sunday in April and having the end remain the last Sunday in October. These start and end dates were in effect from 1987 to 2006. The time was adjusted at 2:00 a.m. local time. By the Energy Policy Act of 2005, daylight saving time (DST) was extended in the United States beginning in 2007. As from that year, DST begins on the second Sunday of March and
