About This Time Zone Pair

US–Europe scheduling requires afternoon US time to coincide with late-afternoon European hours. An additional planning note: the US/Canada and EU switch clocks on different dates — North America transitions about 2–3 weeks before Europe in spring, and roughly 1 week after Europe in fall. During those windows, the offset between London and New York shifts by one hour from what standing calendar invites may show.

London (GMT+1) is 5 hours ahead of New York (EDT). When it's 9:00 AM in London, it's 4:00 AM in New York.

London and New York observe Daylight Saving Time, which means the offset between the two cities may shift by one hour during DST transitions — particularly if the two regions change their clocks on different dates.

The best window for live meetings between London and New York is 2pm–6pm GMT+1 — that's 9am–1pm EDT for New York. Outside this window, async communication or recorded video is more practical.

For one-off conversions, use the converter above. For recurring meetings, export an .ics calendar invite — attendees see the time in their local zone automatically.
