Best Time to Call Between New York and London

Find the optimal overlapping hours for calls and meetings between New York (EST/EDT) and London (GMT/BST).

Best Time to Call Between New York and London

New York and London are separated by 5 hours most of the year. London is always ahead. During daylight saving transitions, the gap briefly shifts to 4 or 6 hours.

The permanent overlap

The most reliable overlap window for business calls is:

9:00 AM – 12:00 PM New York (2:00 PM – 5:00 PM London)

This window works year-round because both sides are within standard business hours.

Morning London, afternoon New York

If the London team prefers morning meetings:

7:00 AM – 9:00 AM London (2:00 AM – 4:00 AM New York — not practical)

This does not work. The gap is too wide for early-morning London meetings.

Best compromise

Schedule calls between 10:00 AM and 11:30 AM Eastern Time. This places the meeting at 3:00 PM to 4:30 PM London time, which is comfortable for both sides.

DST complications

In spring, the US shifts clocks forward 2–3 weeks before the UK. During this gap, the time difference narrows to 4 hours.

In autumn, the UK shifts back 1–2 weeks before the US. The difference temporarily widens to 6 hours.
