Scheduling guide

New York and London sit 5 hours apart for most of the year, which gives you a comfortable 4-hour workday overlap: 9:00 AM to 1:00 PM New York time is 2:00 PM to 6:00 PM London time. That window is the backbone of transatlantic scheduling, and it is why so many US-UK teams default to late-morning Eastern calls.

Watch the daylight saving gap weeks. The US moves its clocks on the second Sunday of March and the first Sunday of November, while the UK moves on the last Sundays of March and October. During those gaps the difference shrinks to 4 hours, so the overlap slides an hour later in New York terms. The calculator above uses your browser's time zone data, so it always shows today's exact window.

Booking tips: aim for 10:00 to 11:00 AM New York time (3:00 to 4:00 PM London). Both sides are past the morning rush and neither is watching the clock. Avoid 8:00 AM New York calls: that is 1:00 PM in London, right in the lunch hour. For recurring standups, pick the middle of the window so a one-hour DST shift never pushes anyone outside work hours.

Most of the year the shared workday runs 9:00 AM to 1:00 PM New York time (2:00 PM to 6:00 PM London). The sweet spot is 10:00 to 11:00 AM New York time, when both sides are alert and unhurried.

How many hours ahead is London from New York?

Five hours for most of the year. During the daylight saving gap weeks in March and late October into early November, the difference shrinks to four hours.

Does daylight saving change the overlap?

Yes, by one hour during the gap weeks when the US and UK clocks are out of sync. The calculator above applies today's DST state automatically.

What if my London colleague can only meet after 6 PM their time?

That is after 1:00 PM New York time, outside the shared workday. Offer an early New York afternoon slot as the compromise, or move the meeting async with a recorded update.
