West Coast US teams coordinating with London offices face one of the wider gaps in common business pairings. This conversion matters for game studios, SaaS companies, and financial firms managing cross-Atlantic workflows.
Add 8 hours to Pacific Time to get London time during standard months. A 9 AM call in San Francisco starts at 5 PM in London, which is the tail end of the UK workday. By 10 AM Pacific, London has clocked out.
The asymmetric DST switches between the US and UK create short transition windows where the gap shrinks to 7 hours. Teams that schedule recurring meetings across this pair should review timing during the last two weeks of March and the last week of October.
