In the United States of America, 17 states (Connecticut, Delaware, Georgia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Vermont, Virginia, and West Virginia) and the District of Columbia are entirely situated within the Eastern Time zone. That is, Eastern Daylight Time (EDT) is UTC – 4 hours. During the daylight saving time, Eastern Time is four hours behind the Coordinated Universal Time. That is, Eastern Standard Time (EST) is UTC – 5 hours. Eastern Standard Time (EST) and Eastern Daylight Time (EDT) are the specific terms used when observing the standard time and daylight saving time respectively.Įastern Time is five hours behind the Coordinated Universal Time (UTC). This time zone is generically called the Eastern Time Zone (ETZ) in the United States of America and Canada. The clock time in the Eastern Time is based on the mean solar time of the 75th meridian west of the Greenwich Observatory in London. It is the time zone that pertains to the east coast of North America.
The Eastern Time (ET) or Eastern Standard Time (EST) is also known as North American Eastern Standard Time. More information about the two time zones will be discussed in this article. However, these times are adjusted by one hour during the day light saving period.
Eastern Time can be calculated by subtracting 5 hours from UTC. Mountain Time can be calculated by subtracting 7 hours from UTC. It is important to note that both Mountain Time and Eastern Time keep time by referring to UTC. In fact, Mountain Time and Eastern Time are actually the ways of keeping time as the rest of the world does by following GMT (Greenwich Mean Time) or UTC (Coordinated Universal Time). The time difference between Mountain Time and Eastern Time, which are two important time zones to North America, is two hours.
