EDT to EST converter
EST is 1 hour behind EDT. These are not two places. They are the same US Eastern clock in its summer and winter forms, one hour apart. The full hour-by-hour table is below, and it reads perfectly well with JavaScript turned off. No account, no email address.
The live converter needs JavaScript. The conversion table below works without it, and so does everything else on this page.

EDT and EST are one clock, six months apart
EDT is what the US east coast runs from the second Sunday in March to the first Sunday in November, at UTC-4. EST is what it runs for the rest of the year, at UTC-5. Only one of the two is ever in force, which is why the gap between them is fixed at one hour and cannot drift the way a gap between two countries can.
That makes this a conversion across the calendar rather than across a map. Ten o’clock on a July morning in New York is EDT. Ten o’clock on a January morning in the same office is EST. The wall clock reads the same both times, and the two moments sit an hour apart in absolute terms.
EDT and EST
- Gap
- Fixed at 1 hour
- In force
- Never both at once
What this means for a booking that crosses the change
A weekly slot booked at 10:00am EDT in October is still a 10:00am slot in November, except that by then it is 10:00am EST. The wall clock holds and the absolute time moves by an hour. That is what almost everybody wants, and it is what a calendar does on its own.
The exception is anybody joining from a zone that does not change on the same weekend. Their 3:00pm becomes your 2:00pm, or your 4:00pm, for however long the two sides are out of step. If a recurring call spans the first Sunday in November, check it against the other end rather than assuming it held.
Both labels describe the same territory, which is the US east coast and eastern Canada, taking in New York, Toronto, Atlanta, Miami and Boston.
EDT to EST: common questions
What time is it in EST when it is 9am EDT?
8:00am. EST is 1 hour behind EDT. The table above runs the same conversion for every hour of the day.
Is EDT to EST ever a different number of hours?
No. EDT and EST are the summer and winter forms of one clock, so the difference is always exactly the hour the clocks move. It is fixed at 1 hour and there is no date on which it is anything else.
Does converting EDT to EST ever change the date?
For most of the working day, no. The two clocks stay on the same calendar day. Late evening and very early morning can straddle midnight, which is why the table above shows the day alongside the time.
What is a good time to schedule a call between EDT and EST?
Any hour you like, because only one of the two is ever in force. The question that matters is the other one: if the call recurs and somebody joins from a zone that changes on a different weekend, check the booking again after the first Sunday in November.
Is this EDT to EST converter free?
Yes, completely. No account, no email address, no trial. The table works with JavaScript turned off and nothing you type is sent anywhere.
