Best overlap: 8:00 AM to 10:00 AM in Shenzhen is 4:00 PM to 6:00 PM in San Francisco.
The sweet spot is 8:00 AM to 10:00 AM Shenzhen time, matching 4:00 PM to 6:00 PM in San Francisco. There's roughly 2 hours to share, so keep agendas lean and meet at 8:00 AM in Shenzhen (4:00 PM in San Francisco) to use every minute. Watch the date, too: while it's still the workday in Shenzhen, San Francisco is already on the previous day. The window above shifts seasonally: San Francisco keeps daylight saving while Shenzhen ignores it.
