Beijing is 6 hours ahead of Brussels
Best overlap: 8:00 AM to 12:00 PM in Brussels is 2:00 PM to 6:00 PM in Beijing.
Shoot for 8:00 AM to 12:00 PM in Brussels; your Beijing colleagues will see that as 2:00 PM to 6:00 PM. A 4-hour overlap gives you a workable daily window; aim for earlier in it to avoid clipping the end of someone's day. Don't be caught out by clock changes — Brussels observes daylight saving and Beijing doesn't, so the offset varies by an hour through the year.
