EST to GMT time
London is five hours ahead of New York on almost every day of the year, so 8:00 AM in New York is 1:00 PM in London. For roughly four weeks a year, in March and around the turn of October and November, the two clocks are only four hours apart.

New York's morning is London's afternoon
For a team based on the East Coast, the usable London window is short: 8:00 AM–noon Eastern equals 1:00–5:00 PM in London. Anything after noon in New York reaches London after the working day. That overlap is also when currency markets are busiest and when the London Stock Exchange, which closes at 4:30 PM local time, is still trading; continuous trading there ends at 11:30 AM New York time.
In spring 2027 the US moves its clocks on March 14 and the UK on March 28, so for those two weeks an 8:00 AM Eastern call lands at noon in London instead of 1:00 PM. Plan any recurring 9:00 AM Eastern call with that in mind.

Early kickoffs, overnight flights
American viewers see British football at breakfast. A Premier League match at 3:00 PM UK time starts at 10:00 AM Eastern and the 12:30 PM early game kicks off at 7:30 AM. NFL games played in London usually kick off at 9:30 AM Eastern, which is 2:30 PM for the crowd in London.
Eastbound flights lose five hours, which is why most leave New York in the evening. A 7:00 PM departure from JFK arrives at Heathrow around 7:00 AM the next morning after about seven hours in the air.
