North American Eastern Time Zone

From Wikipedia, the free encyclopedia

(Redirected from Eastern Standard Time Zone)

The Eastern Time Zone (ET) of the Western Hemisphere falls mostly along the east coast of Northern America and the west coast of South America. Its time offset is UTC-5 during standard time and UTC-4 during daylight saving time. The clock time in this zone is based on the mean solar time of the 75th degree meridian west of the Greenwich Observatory.

In the United States and Canada, this time zone is generically called Eastern Time (ET). Specifically, it is Eastern Standard Time (EST) when observing standard time (Winter), and Eastern Daylight Time (EDT) when observing daylight saving time (Summer).

In the United States, the following states are part of the Eastern Time Zone in their entirety:

Parts of several other states use Eastern Time as well:

nearly all of Florida exept for the west border with Alabama
most of Indiana (all except the Evansville metropolitan area and the suburbs of Chicago, Illinois)
eastern half of Kentucky
all of Michigan except the four Upper Peninsula counties that border Wisconsin (Gogebic, Iron, Dickinson, Menominee). This time zone difference regularly causes confusion among residents of the Upper Peninsula and some have called for the entire Upper Peninsula be placed in the Central Time Zone.
the eastern third of Tennessee, almost but not precisely coterminous with the region legally designated as East Tennessee

[edit] Other countries

The following countries that use Eastern Time Zone include:

Mexico - the eastern state of Quintana Roo also followed EST for a brief period in the 1990s
Panama
Jamaica
Haiti
Cuba
the Bahamas
Not all Caribbean countries observe Daylight saving time. Most Eastern Caribbean states are in the UTC-4 timezone, which is known in North America as the Atlantic Time Zone and is the equivalent of EDT and one hour ahead of EST.
