9am in London is 4pm in Shanghai

When it’s 9am in London, it’s 5pm in Shanghai. Shanghai is 8 hours ahead London. London observes daylight saving time but Shanghai does not, so the gap shifts by one hour during clock changes. The best time to schedule calls between the two cities is 9am to 10am London time (which is 5pm to 6pm in Shanghai). With a large gap separating these two business hubs, most cross-city calls require one team to work outside standard hours. In practice, teams in London tend to take early-morning calls to reach Shanghai during standard afternoon hours, while Shanghai counterparts can schedule near end of day. Having a standing calendar slot for cross-city calls reduces back-and-forth over scheduling and keeps projects moving efficiently.
