London is on GMT+1 (UTC+1) and New York City is on EDT (UTC-4), a gap of 5 hours. London is ahead — so when it is 12:00 in London, it is already 07:00 in New York City. Going the other way, when it is 12:00 in New York City, it is only 17:00 in London.
For calls, video meetings or messages between London and New York City, aim for the overlap in normal waking hours on both sides rather than assuming a shared 9-to-5 — with a 5h gap, one side may need to join early morning or late evening. Business hours in New York City typically start later than in London, so scheduling around late morning to early afternoon in the behind city usually finds the widest overlap.
Note that this 5h difference reflects current UTC offsets and can shift by an hour around daylight saving time (DST) clock changes if only one city observes it.
