Eastern Daylight Time – EDT Time Zone

Eastern Time (ET) or the Eastern Time Zone. This can add a bit of confusion as the term Eastern Time does not differentiate between standard time and Daylight Saving Time, so Eastern Time switches between EST and EDT in areas that use DST during part of the year.

Most North American time zones also have generic terms, including Pacific Time (PT), Mountain Time (MT), Central Time (CT), and Atlantic Time (AT).
