DST in the USA Today

Daylight Saving Time (DST) in the USA starts on the second Sunday in March and ends on the first Sunday in November. The current schedule was introduced in 2007 and follows the Energy Policy Act of 2005.

According to section 110 of the act, the US Department of Transportation (DOT) governs the use of DST. The law does not affect the rights of the states and territories that choose not to observe DST.

Confusing DST Rules

Historically, there were no uniform rules for DST from 1945 to 1966. This caused widespread confusion, especially in transport and broadcasting. The Uniform Time Act of 1966 aligned the switch dates across the USA for the first time.

Following the 1973 oil embargo, the US Congress extended the DST period to 10 months in 1974 and 8 months in 1975, in an effort to save energy.

After the energy crisis was over in 1976, the DST schedule in the US was revised several times. From 1987 to 2006, the country observed DST for about 7 months each year.
