TIME RELATIONSHIP MAP
Why the difference can be four or five hours
New York uses America/New_York; London uses Europe/London. In 2026, the US changes clocks on 8 March and 1 November; the UK changes on 29 March and 25 October. Those schedules create a short mismatch in spring and autumn.
For example, 09:00 in New York becomes 14:00 in London on 15 January 2026, but 13:00 on 15 March 2026. The normal five-hour difference returns after both places have changed clocks.
A late call can arrive on the next day
23:30 in New York on 31 December 2026 is 04:30 in London on 1 January 2027. Always check the displayed date when sending a meeting invitation.

Frequently Asked Questions
- How many hours ahead of New York is London?
- London is usually five hours ahead. The gap becomes four hours during the periods when the US and UK change daylight saving on different dates. Use the local date and time converter for the exact difference.
- What happens to a meeting during a daylight-saving change?
- A meeting kept at the same New York local time can appear one hour earlier in London during the transition mismatch. The converter uses the rules for the selected date, not today's offset.
- Can I convert London time to New York?
- Yes. Select London → New York in the From field, enter a London local date and time, and convert. The result includes both local dates and UTC.
- Why does a local time sometimes occur twice?
- When clocks move back, an hour repeats. The converter asks you to choose the first or second occurrence. When clocks move forward, skipped times are rejected rather than silently changed.
