Geneva is 7 hours behind Shanghai
Best overlap: 3:00 PM to 6:00 PM in Shanghai is 8:00 AM to 11:00 AM in Geneva.
Book within 3:00 PM to 6:00 PM Shanghai time (8:00 AM to 11:00 AM in Geneva) and both teams will be at work. Geneva is 7 hours behind Shanghai, so the practical overlap is about 3 hours — generous enough for meetings, tight enough to be worth booking ahead. Don't be caught out by clock changes — Geneva observes daylight saving and Shanghai doesn't, so the offset varies by an hour through the year.
