Eastern Time Zone

Eastern Time Zone (ET) is the time zone for the eastern part of the Americas including the United States, Canada and parts of South America and the Caribbean. ET is five hours behind UTC in winter, which is called Eastern Standard Time (EST). It is four hours behind UTC during summer Daylight saving time, when it is called Eastern Daylight Time (EDT).

The largest city in the Eastern Time Zone is New York, the largest city in the United States. The New York metropolitan area is the largest in the zone.
