when did the us first start using daylight savings time
History of time in the United States Daylight saving time was established by the Standard Time Act of 1918. The Act was intended to save electricity for seven months of the year, during World War I.[3] DST was repealed in 1919 over a Presidential veto,[4] but standard time in time zones remained in law, with the Interstate Commerce Commission (ICC) having the authority over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.
Veterans Day Congress amended the bill on June 1, 1954, replacing "Armistice" with "Veterans," and it has been known as Veterans Day since.[6][7]
Eastern Time Zone The Uniform Time Act of 1966 ruled that daylight saving time would run from the last Sunday of April until the last Sunday in October in the United States.[3] The act was amended to make the first Sunday in April the beginning of daylight saving time as of 1987.[3] The Energy Policy Act of 2005 extended daylight saving time in the United States beginning in 2007. So local times change at 2:00 a.m. EST to 3:00 a.m. EDT on the second Sunday in March and return at 2:00 a.m. EDT to 1:00 a.m. EST on the first Sunday in November.[3] In Canada, the time changes as it does in the United States.[4][5]
