Standard time in time 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).[1][2] The act also established daylight saving time, itself a contentious idea.
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]
