Understanding the London – New York City Time Difference
London runs on Europe/London, currently BST (UTC+1:00). New York City runs on America/New_York, currently EDT (UTC-4:00). The gap of 5 hours is simply the distance between those two offsets.
Both cities observe Daylight Saving Time, but they don't switch on the same date — so for a few weeks each year the gap between them is different again. The next shift is on Sunday, October 25, 2026, when London adjusts its clocks and the difference becomes 4 hours. Anything scheduled across that date needs checking again.
