Daylight saving right now

Eastern Daylight Time

America/New_York is currently on EDT (UTC-04:00), its daylight-saving clock.

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

EDT is the summer half of US Eastern Time, UTC-4. It runs from the second Sunday in March to the first Sunday in November; outside that window New York is on EST (UTC-5).

Greenwich Mean Time

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

no clock change scheduled — 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.

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

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

GMT to EDT — questions

What time is it in EDT when it is GMT now?
EDT is currently 20:16 on Wednesday, 12 August 2026 (EDT, UTC-04:00), while GMT is 00:16 (UTC+00:00). That is 4 hours behind the source clock right now.
How many hours behind is EDT of GMT?
4 hours at this moment. The gap is not constant across the year: Greenwich Mean Time and Eastern Daylight 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 EDT on daylight saving time right now?
Yes — America/New_York is on EDT (UTC-04:00) right now.
When does EDT next change its clocks?
America/New_York next changes on Sunday, 01 November 2026 at 01:00 local time, when it moves back 60 minutes and the abbreviation becomes EST (UTC-05:00). That is 80 days away. This date comes from the IANA tzdata rules currently in force, so it updates if a government changes the law.
What is the best time to schedule a call between GMT and EDT?
There are 5 hours of overlap where both sides are inside a 09:00-18:00 working day. The longest block is 13:00–18:00 GMT, which is 09:00–14:00 EDT. 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 EDT in code?
Use America/New_York. Abbreviations like EDT 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-04:00 instead will be wrong the moment the rules change.
