Time Zones in United States.
The Eastern Time Zone is also known as Eastern Standard Time (EST) falls mostly along the east coast of North America. Its time offset is −5 hours (UTC/GMT -5) during standard time and −4 hours (UTC/GMT -4) during daylight saving time. The time in this zone is based on the mean solar time of the 75th meridian west of the Greenwich Observatory.
In the United States and Canada, this time zone is generally called Eastern Time (ET). Specifically, it is Eastern Standard Time (EST) when standard time is observed (winter), and Eastern Daylight Time (EDT) when daylight saving time is observed (spring, summer and autumn).
Effective since 2007, the local time changes from EST to EDT at 02:00 LST to 03:00 LDT on the second Sunday in March, and returns at 02:00 LDT to 01:00 LST on the first Sunday in November, in the U.S.A. as well as in Canada.
