San Diego is 15 hours behind Beijing

Best overlap: 8:00 AM to 9:00 AM in Beijing is 5:00 PM to 6:00 PM in San Diego.

Plan around 8:00 AM to 9:00 AM in Beijing, which is 5:00 PM to 6:00 PM in San Diego, to catch everyone during office hours. San Diego is 15 hours behind Beijing. That's only 1 hour of overlap, so pair live calls with async follow-ups to make the most of it. Remember San Diego is a day apart — the previous day — so a late call for Beijing could be the following morning there. Note that San Diego follows daylight saving while Beijing stays put, so the times above drift by an hour seasonally.
