Milan is 6 hours behind Beijing
Best overlap: 2:00 PM to 6:00 PM in Beijing is 8:00 AM to 12:00 PM in Milan.
If you set up a recurring sync, 2:00 PM to 6:00 PM in Beijing (8:00 AM to 12:00 PM in Milan) is the natural home for it. With 4 hours of overlap, 2:00 PM in Beijing (8:00 AM in Milan) is a comfortable, repeatable slot for both sides. Because Milan and Beijing don't both observe daylight saving, plan to re-check the overlap around March and November.
