Best time for work calls

If you are scheduling a call between Seattle and London, there is very limited or no overlap in normal business hours. Consider early-morning or late-evening calls for one side, or use async communication.

Best time for family calls

Scheduling a family call between Seattle and London takes a little planning. Seattle is 8 hours behind London, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Seattle β€” around 7 pm β€” which puts London at 3 am. Someone will need to stretch a little, but at least no one's setting a middle-of-the-night alarm. Weekends tend to give the most flexibility if you can agree on a time in advance.
