Difference Between Eastern Daylight Time (EDT) and Eastern Standard Time (EST) (With Table)

Eastern Daylight Time (EDT) vs Eastern Standard Time (EST)

EST stands for an Eastern Standard Time, and EDT stands for Eastern Daylight Time.

Both Eastern Standard Time and Eastern Daylight Time are used as time zones for the same area.

Yet, both of them cannot be used as synonyms.

They are used for better time management and for convenient international calls, meetings, and conferences.

These time zones are determining by the geographical conditions and location of our planet and the sun as well as the moon.

 The difference between both the time zones is that of a single letter.

Understandably, confusion can arise as to when do we apply the Eastern Standard Time and when the Eastern Daylight Time. 

The key difference between Eastern Standard Time and Eastern Daylight Time lies in the fact that although they are used for the same time zones, they are used at different times of the year.

The Eastern Standard Time is used during the fall-winter season. It is used from the first Sunday of November.

Eastern Daylight Time is also an hour ahead of the Eastern Standard Time.

For example: when Eastern Daylight Time is used, the international meetings are held between 10 am to 6 pm whereas for Eastern Standard Time the same meeting and conference are held between 9 am to 5 pm.

According to the coordinated universal time, the Eastern Daylight Time is four hours behind it, whereas the Eastern Standard Time is five hours behind coordinated universal time.

EST and EDT are not used in any other part of the world apart from eastern countries.
