Are you tired of being left in the dark when it comes to understanding time zones? Have you ever found yourself puzzled by the acronyms EDT and EST, wondering what they really mean?
EDT is the time zone observed during daylight saving time in regions located in the Eastern Time Zone, while EST is the standard time zone observed during the non-daylight saving period in regions located in the Eastern Time Zone.
EDT vs. EST
| EDT (Eastern Daylight Time) | EST (Eastern Standard Time) |
|---|---|
| EDT is the time zone observed during the daylight saving time period in the Eastern Time Zone. It is 4 hours behind Coordinated Universal Time (UTC-4). | EST is the time zone observed during the standard time of the year in the Eastern Time Zone. It is 5 hours behind Coordinated Universal Time (UTC-5). |
| It is used during the daylight saving time months, typically from the second Sunday in March until the first Sunday in November. | It is used during the non-daylight saving time months, typically from the first Sunday in November until the second Sunday in March. |
| EDT is the time zone that takes effect during daylight saving time, providing an additional hour of daylight in the evenings. During this period, the clocks are set forward by one hour. | EST does not observe daylight saving time, so the time remains constant throughout the year without any adjustments to the clocks. |
| It is observed in regions within the Eastern Time Zone, which includes areas on the East Coast of the United States and Canada, such as New York, Washington D.C., and Toronto. | It is also observed in regions within the Eastern Time Zone but specifically during the standard time of the year when daylight saving time is not in effect. It follows the same geographical boundaries as EDT. |
| To convert from EDT to Coordinated Universal Time (UTC), add 4 hours to the EDT time. For example, 12:00 PM EDT is 4:00 PM UTC. | To convert from EST to Coordinated Universal Time (UTC), add 5 hours to the EST time. For example, 12:00 PM EST is 5:00 PM UTC. |
| It is used in regions that participate in daylight saving time to make better use of daylight during the longer days of spring, summer, and early fall. The clocks are set forward to extend daylight hours. | It is used in regions that do not observe daylight saving time or have opted out of the practice. It is the standard time used in these regions throughout the year. |
What is EDT and EST?
EDT (Eastern Daylight Time) and EST (Eastern Standard Time) are two different time zones used in regions within the Eastern Time Zone of North America. EDT is observed during daylight saving time, which typically starts on the second Sunday in March and ends on the first Sunday in November. During EDT, the time is UTC-4 hours, meaning it is four hours behind Coordinated Universal Time (UTC).
EST is used during the non-daylight saving period, encompassing the rest of the year outside of daylight saving time. During EST, the time is UTC-5 hours, making it five hours behind Coordinated Universal Time (UTC). The switch between EDT and EST occurs twice a year, with clocks moving forward one hour during daylight saving time (EDT) and moving back one hour during the end of daylight saving time (EST).
History of EDT and EST
EDT was originally created as a way to save energy during the summer months. By setting clocks ahead an hour, people would use less electricity because they would be more likely to be outside during daylight hours. This practice eventually spread to other parts of the country, but it wasn’t until 1966 that Congress officially made daylight saving time law.
EST, on the other hand, is used by most of the country during the winter months. It begins on the first Sunday in November and ends on the second Sunday in March. During EST, clocks are set an hour back so that people can enjoy an extra hour of sleep!
How does daylight saving time impact EDT and EST?
Daylight saving time (DST) is the practice of advancing clocks during warmer months so that darkness falls later in the day. The idea is that people can take advantage of natural sunlight and save energy by using less artificial light. DST generally begins on the second Sunday in March and ends on the first Sunday in November.
During DST, EDT becomes EDT +1 hour while EST becomes EDT – 1 hour. This can be confusing for people who are used to thinking of EST as being behind EDT by one hour. For example, if it is 5:00 pm EDT, it will be 6:00 pm EDT during DST. However, if it is 5:00 pm EST, it will be 4:00 pm EST during DST.
When Do You Use EDT or EST?
EDT stands for Eastern Daylight Time and EST stands for Eastern Standard Time. EDT is one hour ahead of EST. The reason for this is that during daylight saving time, which occurs from March to November, the clocks are set one hour ahead. This means that when it is noon EDT, it is only 11 am EST.
In practical terms, this means that if you are in New York City, which is in the Eastern time zone, you would use EDT during daylight saving time and EST the rest of the year. If you are planning a conference call or other event with someone in another part of the country, it’s important to check whether they are on EDT or EST so that you can plan accordingly.
Common misconceptions about EDT and EST
Firstly, EDT is not a time zone in its own right – it is simply a designation used during daylight saving time in the eastern United States.
Secondly, EST is not a time zone either – it is the official time zone for the eastern United States (without daylight saving time).
EDT and EST are not always exactly one hour apart – due to the way daylight saving time works, they can actually be two or even three hours apart at certain times of the year.
Key differences between EDT and EST
Time Offset:
- EDT: Eastern Daylight Time is UTC-4 hours, meaning it is four hours behind Coordinated Universal Time (UTC).
- EST: Eastern Standard Time is UTC-5 hours, meaning it is five hours behind Coordinated Universal Time (UTC).
Observance:
- EDT: EDT is observed during daylight saving time, which typically starts on the second Sunday in March and ends on the first Sunday in November.
- EST: EST is used during the non-daylight saving period, which includes the rest of the year outside of daylight saving time.

Conclusion
EDT is observed during daylight saving time, UTC-4 hours, while EST is used during the non-daylight saving period, UTC-5 hours. The switch between EDT and EST occurs twice a year, with clocks adjusted forward during daylight saving time and backward to standard time. Understanding these differences ensures accurate timekeeping and scheduling in regions within the Eastern Time Zone.
