QUESTIONS

How many hours is Shanghai ahead of San Francisco?

Shanghai is 15 hours ahead of San Francisco. That's calculated from each city's current UTC offset (UTC-7 for San Francisco, UTC+8 for Shanghai).

Does the time difference between San Francisco and Shanghai change during the year?

It can. San Francisco observes daylight saving time, so the gap shifts by an hour when clocks change. The live clocks above always reflect the current, correct difference.

What's the best time to schedule a meeting between San Francisco and Shanghai?

There's no window where both San Francisco and Shanghai are in standard 9-to-5 hours at the same time, so a live call means one side joins early or late. Converge can find the least-bad slot from everyone's real availability.
