Best Meeting Time: New York to London
🕐 Live Timezone Overlap: New York & London
New York and London sit 5 hours apart, with London ahead. That gap shapes daily life for anyone coordinating across the Atlantic. A New York team starting at 9am ET connects with London colleagues already well into their afternoon. For global finance desks, this overlap is a busy period: the NYSE opens at 9:30am ET, which lands at 2:30pm in London, aligning with the City of London's attention to New York. Getting the timing right is a practical matter, not a formality.
Time Difference: New York and London
London is currently 5 hours ahead of New York. The live offsets are New York UTC-4 and London UTC+1. New York observes daylight saving and London also observes daylight saving, so the offset shifts twice a year if both sides aren't already aligned.
Both cities observe daylight saving time, but their clocks do not change on the same weekend. London moves its clocks one week earlier than New York each autumn. During that brief window, the offset narrows from 5 hours to 4 hours. For the rest of the year, London runs 5 hours ahead of New York when both are on summer time, and 5 hours ahead again when both revert to standard time. The autumn changeover week is the one period to watch carefully.
Best Times to Meet
The working-hours overlap between New York and London is 4 hours: 9am to 1pm in New York, which is 2pm to 6pm in London. Inside that 4-hour window, 9am to 11am New York time is generally the cleanest slot. London finance teams note that informal meetings between 5pm and 6pm are common, so the later end of the window suits them. New York teams tend to run client meetings in the 4 to 6pm slot to bridge with European partners, but that falls outside London's working hours.

Tips for Scheduling Across New York and London
- Book New York to London calls between 9am and 11am ET to avoid London's post-lunch lull and Friday wind-down.
- The autumn clock-change week creates a temporary 4-hour gap: double-check calendar invites that week.
- New York's NYSE open at 9:30am ET corresponds to 2:30pm London time, a natural anchor for finance calls.
- Avoid scheduling across the fourth Thursday in November for New York; London teams will be at their desks but New York will not.
- London finance contacts are often available up to 6pm; use the 12pm to 1pm ET slot to catch them before their day ends.
Public Holidays and Working Weeks
Both cities follow a Monday to Friday working week, with standard hours of 9am to 6pm. London offices often wind down early on Fridays. Coming up on the holiday calendar: New York observes Independence Day on 4 July and Thanksgiving on the fourth Thursday in November; London has Christmas Day on 25 December and the May Bank Holiday on the first Monday in May. Cross-city meetings should account for both sets of dates, since a busy period in one city can easily catch the other off guard.
