About This Time Zone Pair
US–Europe scheduling requires afternoon US time to coincide with late-afternoon European hours. An additional planning note: the US/Canada and EU switch clocks on different dates — North America transitions about 2–3 weeks before Europe in spring, and roughly 1 week after Europe in fall. During those windows, the offset between London and San Francisco shifts by one hour from what standing calendar invites may show.
London (GMT+1) is 8 hours ahead of San Francisco (PDT). When it's 9:00 AM in London, it's 1:00 AM in San Francisco.
London and San Francisco observe Daylight Saving Time, which means the offset between the two cities may shift by one hour during DST transitions — particularly if the two regions change their clocks on different dates.
The best window for live meetings between London and San Francisco is 5pm–6pm GMT+1 — that's 9am–10am PDT for San Francisco. Outside this window, async communication or recorded video is more practical.
