Daylight saving right now

Greenwich Mean Time

Etc/GMT is currently on GMT (UTC+00:00).

no clock change scheduled — this zone is fixed at UTC+00:00

GMT is UTC+0 and never shifts. The UK observes GMT in winter only — in summer it is on BST (UTC+1), so "GMT" on a British invite dated in July usually means BST.

Eastern Standard Time

America/New_York is on EDT (UTC-04:00).

next change: Sun, 1 Nov 2026 01:00 local → EST (80 days)

EST is the winter half of US Eastern Time. From the second Sunday in March to the first Sunday in November, New York is on EDT (UTC-4) instead — so half the year an "EST" meeting invite is off by an hour.

Best time to call green = 09:00–18:00 on both sides

5 overlapping working hours. The longest run is 09:00–14:00 EST, which is 13:00–18:00 GMT.

EST to GMT — questions

What time is it in GMT when it is EDT now?
GMT is currently 00:22 on Thursday, 13 August 2026 (GMT, UTC+00:00), while EST is 20:22 (UTC-04:00). That is 4 hours ahead of the source clock right now.
How many hours ahead is GMT of EST?
4 hours at this moment. The gap is not constant across the year: Eastern Standard Time and Greenwich Mean Time change clocks on different dates (or one of them not at all), so a difference you hard-code in summer can be an hour wrong in winter. The table on this page is computed from the current tzdata rules, not from a fixed offset.
Is GMT on daylight saving time right now?
No. Etc/GMT is on GMT (UTC+00:00) at the moment.
Does GMT observe daylight saving time?
No. Etc/GMT stays on UTC+00:00 all year, so the difference from EST only moves when EST itself changes.
What is the best time to schedule a call between EST and GMT?
There are 5 hours of overlap where both sides are inside a 09:00-18:00 working day. The longest block is 09:00–14:00 EST, which is 13:00–18:00 GMT. Use the calendar buttons above to drop it straight into Google Calendar, Outlook or an .ics file.
Which IANA timezone name should I use for GMT in code?
Use Etc/GMT. Abbreviations like GMT are ambiguous and not resolvable by most libraries — Python's ZoneInfo, Java's ZoneId, Go's time.LoadLocation and JavaScript's Intl all expect the IANA name. Hard-coding UTC+00:00 instead will be wrong the moment the rules change.
