Keeping UK hours with America in the picture

For anyone in Britain, the US is five hours behind at its nearest point and eight at its furthest. The East Coast lines up with your afternoon; everything else happens while you are asleep.

Doing business with the US

Your mornings are quiet from America; your afternoons are busy.

  • New York’s 9 AM is 2:00 PM in the UK, so calls realistically start after lunch
  • An email sent at 4 PM UK reaches New York at 11:00 AM and may get a reply before you finish
  • US colleagues work until 10:00 PM UK time, so replies keep landing through your evening

Watch for US public holidays that the UK does not share, such as Thanksgiving (the fourth Thursday of November) and 4 July, when American offices are closed.

American sport on UK time

NFL and NBA schedules are set for American evenings, which land late in yours.

  • Sunday NFL early games, 1 PM ET = 6:00 PM UK
  • Late NFL games, 4:25 PM ET = 9:25 PM UK
  • Sunday Night Football, 8:20 PM ET = 1:20 AM (next day) UK
  • The Super Bowl in February usually kicks off around 11:30 PM UK time

Calling friends and family in America

Your evening is their afternoon, which is the easiest time for both sides.

  • UK 7–10 PM = East Coast 2:00 PM–5:00 PM
  • UK 7–10 PM = West Coast 11:00 AM–2:00 PM
  • Before 1 PM UK, nobody on the East Coast is up for a chat: 8 AM UK is 3:00 AM in New York

US releases and events

Big American launches are timed for US audiences.

  • Many streaming shows drop at midnight Pacific = 8:00 AM UK (8:00 AM in summer)
  • A 9 PM ET TV premiere = 2:00 AM (next day) UK
  • Tech keynotes at 10 AM Pacific in September = 6:00 PM UK

The week the gap shrinks to four hours

The UK puts its clocks back on the last Sunday of October. America waits until the first Sunday of November. For that one week, and for about two weeks in March going the other way, New York is only 4 hours behind.

This autumn: from Sunday 25 October to Saturday 31 October 2026, a 2 PM meeting in the UK is 10:00 AM in New York, not 9:00 AM. Everything goes back to 5 hours on Sunday 1 November. Next spring the short gap runs from 14 to 27 March 2027.

Calendar invites created in a time zone move by themselves. The ones that go wrong are times written into an email or a chat message, so double-check anything agreed in words during those weeks.

If your country uses GMT all year

The UK is only on GMT in winter, but several countries keep it all year and never change their clocks: Iceland, Ghana, Senegal, Côte d’Ivoire and Sierra Leone among them. For them the gap to New York changes only when the US changes.

From early November to mid-March, Reykjavik or Accra is 5 hours ahead of New York: 2 PM there is 9:00 AM in New York. From mid-March to early November it is 4 hours ahead: 2 PM is 10:00 AM. Use the converter above with the city itself (type “Accra” or “Iceland”) rather than London, so the summer hour is handled correctly.

UK time to US time, every hour

New York for most of the year, New York during the out-of-step weeks, and Los Angeles for good measure. Green rows are when both London and New York are at work.
