US–Europe daylight saving gap in 2026
The US changes clocks on March 8 and November 1. The UK and EU change on March 29 and October 25. A New York–London meeting shifts by one hour during the weeks between those dates.
9:00 AM in New York, throughout 2026
| Meeting date | Time in London | New York → London gap |
|---|---|---|
| January 1 – March 7 | 2:00 PM | 5 hours |
| March 8 – March 28 | 1:00 PM | 4 hours |
| March 29 – October 24 | 2:00 PM | 5 hours |
| October 25 – October 31 | 1:00 PM | 4 hours |
| November 1 – December 31 | 2:00 PM | 5 hours |
These rows compare 9:00 AM New York time. The precise transition hours on March 8, March 29, October 25 and November 1 need a date-and-time conversion.
Why the one-hour shift happens
New York enters daylight saving on March 8, three weeks before London does on March 29. London leaves daylight saving on October 25, one week before New York does on November 1. During both gaps, New York is on EDT while London is on GMT.
For example, a recurring 9:00 AM New York call appears at 2:00 PM in London on March 3, 1:00 PM on March 17, and 2:00 PM on March 31. In fall it is 2:00 PM on October 20, 1:00 PM on October 27, and 2:00 PM on November 3.
How to keep a recurring invite clear
Include the meeting date and a named city time zone, such as America/New_York or Europe/London. Check the invite on each transition week. The New York to London converter and London to New York converter handle either direction. For more cities, use the meeting planner.
MeetAcross calculates with the time-zone rules available in your browser. Keep your browser and operating system updated when governments change those rules.
