About This Time Zone Pair

US–Europe calls and meetings require 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 Los Angeles shifts by one hour from what standing calendar invites may show.

London (GMT+1) is 8 hours ahead of Los Angeles (PDT). When it's 9:00 AM in London, it's 1:00 AM in Los Angeles.
