Also known as: Eastern Standard Time (EST) and Eastern Daylight Time (EDT)
The term Eastern Time (ET) is often used to denote the local time in areas observing either Eastern Daylight Time (EDT) or Eastern Standard Time (EST).
In other words, in locations observing Daylight Saving Time (DST) during part of the year, Eastern Time is not static but switches between EDT and EST.
Eastern Time UTC Offset
Eastern Standard Time is 5 hours behind Coordinated Universal Time (UTC).
Eastern Daylight Time is 4 hours behind UTC.
What Is Eastern Time?
Eastern Time (ET) is the easternmost time zone in the United States. It is also used in Canada.
Almost half of the population in the USA live in the ET time zone. It spans from northern Canada and all the way south to Panama near the equator.
In North America, Eastern Time shares a border with Atlantic Time (AT) in the east and with Central Time (CT) in the west.
What Does ET Time Zone Mean?
Unlike other time zone denominations, which have a fixed time, Eastern Time refers to a geographical area where the time changes twice yearly as Daylight Saving Time (DST) begins and ends. Eastern Standard Time is UTC-5, while Eastern Daylight Time is UTC-4.
Most North American time zones also have generic terms, including Pacific Time (PT), Mountain Time (MT), Central Time (CT), and Atlantic Time (AT).
Converting Eastern Time to Other US Time Zones
- Eastern Time (ET) is 1 hour ahead of Central Time (CT).
To convert ET to CT, you have to subtract one hour.
- Eastern Time (ET) is 2 hours ahead of Mountain Time (MT).
To convert ET to MT, you have to subtract two hours.
- Eastern Time (ET) is 3 hours ahead of Pacific Time (PT).
To convert ET to PT, you have to subtract three hours.
