Shenzhen is 7 hours ahead of Munich
Best overlap: 8:00 AM to 11:00 AM in Munich is 3:00 PM to 6:00 PM in Shenzhen.
Schedule calls for 8:00 AM to 11:00 AM in Munich — your colleagues in Shenzhen will be online from 3:00 PM to 6:00 PM. Shenzhen is 7 hours ahead of Munich, which gives you a solid 3-hour window. Book earlier in it and neither side is rushing. Finally, Munich observes daylight saving and Shenzhen doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
