How many hours ahead is London of New York?

Why do the times differ between London and New York?

London, United Kingdom (GMT+1) is 5 hours ahead of New York, United States (GMT-4).

How is this conversion worked out?

New York runs on America/New_York (GMT-4) and London on Europe/London (GMT+1), a difference of 5 hours this week. The peak hours themselves are measured in New York local time, and that figure never moves. What moves is the reading on your own clock, twice a year, when either place changes for daylight saving. The two places do not always change on the same date, so for a couple of weeks each spring and autumn the difference is an hour off its usual value; that is why these pages are rebuilt every week rather than computed once.

Does any platform peak on a different day in London?

No platform's best slot crosses midnight between New York and London, so the day of the week is the same on both clocks. Converted times use the offsets in force this week (GMT+1 and GMT-4). The audience-clock column never changes; the converted column is rebuilt weekly so it stays right across daylight-saving changes. The same times apply across New York's timezone, including Washington DC, Miami, Atlanta and Boston.
