Eastern Time Zone

Eastern Daylight Time is four hours behind the Coordinated Universal Time standard, written as an offset of UTC - 4:00. That means to find the standard time in the zone you must subtract four hours from Coordinated Universal Time.

Territories observing the time zone are primarily in North America and the Caribbean. It runs through several U.S. states, and Caribbean islands like the Bahamas and Haiti.

Depending on where the time zone is being referenced, it may be called one of these additional names:

Eastern Daylight Savings Time or EDST

North American Eastern Daylight Time or NAEDT

Heure Avancée de l'Est or HAE (in French)

Tiempo de verano del Este or EDT (in Spanish)

In many of the areas where this time zone is used, during fall to winter months Eastern Standard Time, or EST, is observed, and then during Daylight Saving (spring to summer months) Eastern Daylight Time or EDT is used.
