What Is Eastern Daylight Time?

Eastern Daylight Time is the easternmost time zone in the United States. It is also used in Canada.

It covers all or parts of 23 states in the US and three provinces or territories in Canada. It is also used in the Caribbean.

Almost half of the population in the USA live in the EDT time zone. The time zone spans from northern Canada to Haiti.

In North America, Eastern Standard Time shares a border with Atlantic Daylight Time (ADT) in the east and with Central Daylight Time (CDT) in the west.


Eastern Daylight Time (EDT) is a North American time zone in use from the second Sunday in March to the first Sunday in November during Daylight Saving Time (DST). Eastern Standard Time (EST) is used during the remainder of the year.

EDT Is the Eastern Time Zone

In everyday usage, EDT is often referred to as Eastern Time (ET) or the Eastern Time Zone. This can add a bit of confusion as the term Eastern Time does not differentiate between standard time and Daylight Saving Time, so Eastern Time switches between EST and EDT in areas that use DST during part of the year.

Most North American time zones also have generic terms, including Pacific Time (PT), Mountain Time (MT), Central Time (CT), and Atlantic Time (AT).
