Time Zone Converter: Eastern Standard Time to Greenwich Mean Time

This page is designed to provide you with up-to-date clocks that accurately portray the difference between Eastern Standard Time and Greenwich Mean Time at the current moment in the day. We also provide you with a chart the showcases conversions for each hour across both zones to help you quickly convert any and all times you may need.

During the winter and spring months, the standard Eastern zone is observed on the east coast of America, but during the summer months, it changes to EDT to observe the time change. The Atlantic ocean separates these two time zones.

When converting from EST to GMT, there is a five hour difference. The former is UTC -5:00 while the latter is UTC 0:00, it is where the prime meridian is located and represents the zero-point from which the other zones are drawn.

An example for you:

If it is 12 A.M in Eastern Standard Time, then it will be 5 A.M in Greenwich Mean Time. During the summer months, the time change results in a four hour difference between the two since the Eastern zone moves an hour forward in the spring.

Geographically, this is located on the Eastern coast of the North American continent, but it also extends down into the Caribbean and up into Canada. On a global map, the Greenwich time zone is located at zero degree longitude and the Eastern time zone is located at 75 degrees west.

There is a great deal of history in this part of the world. For example, the original thirteen colonies of the United States were all located within this zone on the east coast of the continent. It was this colonies that would go on to wage war against the British to gain independence and bring about the nation that occupies this continent today.

The range of climate within the locations here is staggering. It is classified as a temperate humid climate that enjoys hot summers and winters that range from cool to very cold. The southern location have a tropical climate that makes them major tourist destinations, while the northern areas have major cities and significant snowfall.

Yet another area rife with historical significance, this time zone represents the place where the concept was born. Originally, before Coordinated Universal Time (UTC) was implemented, this was where the time standard was located. It was based on the solar time established at the Greenwich Royal Observatory.

The largest city in this zone is London in the United Kingdom. Other notable cities in this zone include Abidjan, Dakar, Grand Dakar, and Accra.

It is unique in that it has no offset from UTC. It is written as 0:00, set at the zero point of the time zones. Solar methods of telling time became obsolete when technology afforded us more accurate options. It is still observed by astronomers.
