Quick answer
3 PM GMT is 10 AM EST in New York (winter). During summer (BST and EDT), 3 PM BST is still 10 AM EDT. This is one of the most popular UK–US East Coast meeting slots: London mid-afternoon and New York mid-morning, with both sides fully in the working day.
3 PM GMT to New York: what to know
3 PM GMT / 10 AM ET is widely regarded as the sweet spot of the London–New York overlap window. London is in mid-afternoon with time for pre-call work and post-call follow-up. New York has had two hours of the working day and is in a productive mid-morning window. Many UK–US recurring meetings are anchored at this slot.
The 5-hour GMT/BST to EST/EDT gap is consistent year-round because both the UK and US East Coast observe daylight saving on the same schedule. There is a brief transition window in spring and autumn (usually 1–2 weeks) when the clocks change on different dates — check exact dates with the Meeting Time Finder if you have a time-sensitive call.
