Timezone abbreviation
EDT Timezone
Eastern Daylight Time is commonly shown as EDT and has an offset of UTC-04:00. EDT is used in parts of North America during daylight saving time.
When to use it
EDT in real schedules
Use EDT for summer daylight time in eastern North America. For recurring meetings, use a city name instead of the abbreviation.
Daylight saving
EDT is the daylight saving counterpart to EST.
Avoid abbreviation mistakes
Timezone abbreviations are compact, but they are not always unique and they do not always describe daylight saving behavior. For exact meetings, choose a city and date in the converter. That lets the timezone database apply the correct local rules instead of relying on a fixed abbreviation.
