New York and London Time Difference: Scheduling Across the Atlantic
The time difference between the two cities is not constant year-round. See how to avoid confusion caused by daylight saving time switches.
How Many Hours Apart Are They Usually?
London is usually five hours ahead of New York. For example, 9:00 AM in New York usually corresponds to 2:00 PM in London. But “usually” is important: the two cities do not switch to daylight saving time on the same day.
During the brief period when the US and UK switch dates are out of sync, the time difference may become four hours. The exact dates differ from year to year.
Check the Date Before Scheduling a Meeting
First determine the meeting date, then convert using city names. Try to write the invitation as “New York local time” and “London local time,” along with the date, to avoid ambiguity from abbreviations.
If a meeting recurs periodically, reconfirm it before each spring and autumn clock adjustment to reduce unexpected absences.
