Best overlap: 8:00 AM to 11:00 AM in Amsterdam is 3:00 PM to 6:00 PM in Shenzhen.
Book within 8:00 AM to 11:00 AM Amsterdam time (3:00 PM to 6:00 PM in Shenzhen) and both teams will be at work. Shenzhen is 7 hours ahead of Amsterdam, so the practical overlap is about 3 hours — generous enough for meetings, tight enough to be worth booking ahead. Daylight saving complicates things slightly: Amsterdam observes it, Shenzhen doesn't, so the difference flexes by an hour part of the year.
