Time difference & DST
London is 5 hours ahead of New York for most of the year, briefly narrowing to 4 hours during the transition weeks in March and November when the two cities' daylight saving calendars don't line up. This is the busiest transatlantic time-zone pair in global finance and media.
Both cities observe daylight saving time but the US moves forward two weeks earlier than the UK in spring and back one week earlier in autumn. During those windows the London–New York offset temporarily shifts to 4 hours.
