Best Time to Call the USA from the UK
The USA spans multiple time zones, so the best UK time to call depends heavily on whether your contact is on the East Coast, West Coast or somewhere in between.
Quick answer
- UK afternoon is usually best for US East Coast calls.
- UK late afternoon or early evening is often needed for US West Coast calls.
- Daylight saving can temporarily change the time difference.
East Coast calls
For New York, Boston, Washington and other East Coast locations, UK afternoon is usually the cleanest meeting window. It avoids early starts in the USA and avoids late evening in the UK.
West Coast calls
For Los Angeles, San Francisco and Seattle, UK late afternoon or early evening is often required. A meeting that feels normal in California may feel late for a UK attendee.
Multi-state calls
If several US attendees are spread across time zones, use the meeting planner rather than relying on one remembered time difference.
Suggested window
For most UK to US business calls, test 15:00 to 18:00 UK time first, then adjust depending on whether the US attendee is East Coast or West Coast.
