Shanghai is 7 hours ahead of Prague
Best overlap: 8:00 AM to 11:00 AM in Prague is 3:00 PM to 6:00 PM in Shanghai.
Schedule calls for 8:00 AM to 11:00 AM in Prague — your colleagues in Shanghai will be online from 3:00 PM to 6:00 PM. Shanghai is 7 hours ahead of Prague, which gives you a solid 3-hour window. Book earlier in it and neither side is rushing. Because Prague and Shanghai don't both observe daylight saving, plan to re-check the overlap around March and November.
