When New York and London are four hours apart in 2026
See when a 09:00 New York meeting becomes 13:00 in London in 2026, with exact dates for the spring and autumn clock-change gaps.
The usual five-hour gap temporarily becomes four
For a meeting at 09:00 in New York, London’s corresponding time is 13:00 from 8–28 March and 25–31 October 2026, inclusive. On the other dates of 2026, that meeting is at 14:00 in London. These date ranges describe this meeting time; the offset changes themselves happen overnight.
New York starts daylight saving on 8 March and ends it on 1 November in 2026. The UK changes on 29 March and 25 October. The different weekends create two periods when a recurring call shifts for colleagues across the Atlantic.
A 09:00 New York meeting through 2026
Keep the organizer’s time fixed and compare the receiving city. All London times below are on the same calendar date as New York.
| New York meeting dates | London time | London ahead by |
|---|---|---|
| 1 January–7 March | 14:00 | 5 hours |
| 8–28 March | 13:00 | 4 hours |
| 29 March–24 October | 14:00 | 5 hours |
| 25–31 October | 13:00 | 4 hours |
| 1 November–31 December | 14:00 | 5 hours |
The exact transition moments matter overnight
The spring four-hour interval begins at 07:00 UTC on 8 March and ends at 01:00 UTC on 29 March. The autumn interval begins at 01:00 UTC on 25 October and ends at 06:00 UTC on 1 November. Each end instant belongs to the restored five-hour difference.
For an overnight shift, broadcast, or early flight, use the actual time as well as the date. A date-only rule can be wrong before or after the transition on that Sunday. The clock-change calendar lists exact instants and the local readings on either side.
Decide which city owns a recurring meeting
A call that stays at 09:00 New York moves in London during these intervals. A call that stays at 14:00 London instead moves to 10:00 New York. Both choices are consistent; the organizer needs to decide which local commitment takes priority.
Set the recurring event’s time zone to that city in your calendar. Check the occurrences on both sides of each transition and tell participants about any shift. The meeting planner’s weekly preview can help compare upcoming occurrences; its calendar download creates a single event.
Do not apply this table to every US location or every year. Choose the actual participant cities and meeting date when checking another route or a future schedule.
