Are EDT and EST the Same?

No. Both refer to the Eastern Time zone but at different times of year:

  • EST (Eastern Standard Time): UTC-5. Winter — first Sunday of November to second Sunday of March.
  • EDT (Eastern Daylight Time): UTC-4. Summer — second Sunday of March to first Sunday of November.

The difference is exactly one hour. EDT is one hour ahead of EST.
