If we look at EST meaning: it means Eastern Standard Time. This time zone is applied in the fall and winter seasons and used for all the eastern parts of the world. It is also one hour behind eastern daylight time and five hours behind the coordinated universal time. When Eastern Standard Time is in effect, the time for all the international conferences is between 10 am to 6 pm. This time zone is used in Central America, the Caribbean and in North America. In these areas, the time is switched to Eastern daylight time on the second Sunday of March; hence it creates an hour gap. EDT is also very helpful in time management and keeps you up to date for convenient international calls and meetings.
