Convert New York and London time
New York and London time difference
London is normally five hours ahead of New York. For short periods in March and late October or early November, the gap is four hours because the U.S. and U.K. start and end daylight saving on different dates. A fixed “add five hours” rule can therefore be wrong.
Best meeting times
When the gap is five hours, 9:00 AM–12:00 PM in New York is 2:00 PM–5:00 PM in London. That is the clearest overlap for ordinary office hours. Convert the actual meeting date above before sending the invitation.
How this converter works
The selected wall-clock time is interpreted in America/New_York or Europe/London, then formatted in the other IANA zone. If a spring clock change makes a time nonexistent, the tool asks for another time rather than silently moving it.
Frequently asked questions
Is New York always five hours behind London?
No. The usual difference is five hours, but it becomes four during the weeks when only one city has changed its clocks.
Can the converted date change?
Yes. Late-evening London times can be the same afternoon in New York, while late-evening New York times can be the next calendar day in London.
