North American Eastern Standard Time Zone

From Wikipedia, the free encyclopedia.

EST is UTC-5

The North American Eastern Standard Time Zone (abbreviated EST) is a geographic region that keeps time by subtracting five hours from Coordinated Universal Time (UTC) resulting in UTC-5. There are also Eastern Standard Time Zones in Australia and Brazil.

In the United States, the following states are part of the Eastern Standard Time Zone: Connecticut, Delaware, Georgia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Vermont, Virginia, West Virginia

Additionally, the eastern half of Kentucky, the eastern quarter of Tennessee, the majority of Florida, and all of Michigan except the four Upper Peninsula counties that border Wisconsin (Gogebic, Iron, Dickinson, Menominee) are part of the Eastern Standard Time Zone. The parts of these states not in the Eastern Standard Time Zone are in the Central Standard Time Zone.

Most of Indiana (all except the Chicago and Evansville metro areas) is part of the Eastern Standard Time Zone. However, most of that portion of the state does not observe Daylight Saving Time (DST). Areas of the state in close proximity to the metro areas of Cincinnati and Louisville do observe DST. Legislation recently passed in Indiana will put the entire state on Daylight Saving Time beginning in 2006.

Other parts of the world that keep time by subtracting five hours from UTC include Cuba, most of the Canadian provinces of Quebec and Ontario, the Bahamas, Colombia, Ecuador (except Galápagos), Peru, Jamaica, Haiti, and Panama.
