EDT to GMT Converter

It takes three quick steps:

1. Click the EDT field on the left and pick the time you want to convert.
2. The matching GMT time updates on the right automatically — there’s no button to press.
3. Need a different day? Click the date field and the result follows, rolling over if it crosses midnight.

GMT is 4 hours ahead of EDT. In everyday terms, once you know the time on one side you just add 4 hours to get the other — so a call between New York and London (winter) is always 4 hours apart.

Right now the time in Greenwich Mean Time (GMT) is Monday, June 29, 2026 · 5:53:55 PM. It ticks every second, so you’re always looking at the live GMT clock.

And in Eastern Daylight Time (EDT), it’s currently Monday, June 29, 2026 · 1:53:55 PM. Compare the two and the 4 hours gap is easy to see.

For example, a 9:00 AM EDT meeting takes place at 1:00 PM GMT. The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.

The labels EDT and GMT are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.

Every conversion here is calculated from the IANA time zone database — the same source your phone, computer, and browser rely on. Plenty of tools hard-code a single offset, which quietly goes wrong whenever a region changes its rules or flips for daylight saving. We follow the real rules instead, so EDT to GMT stays accurate for today and for any past or future date you type in.
