The Eastern Standard Time Zone (abbreviated EST) is a geographic region that keeps time by subtracting five hours from Coordinated Universal Time (UTC).

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 Gogebic, Iron, Dickinson and Menominee counties 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 Gary, Indiana and Evansville, Indiana 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, Ohio and Louisville, Kentucky do observe DST.

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, Peru, Jamaica, Haiti, and Panama.
