Shenzhen is 7 hours ahead of Oslo
Best overlap: 8:00 AM to 11:00 AM in Oslo is 3:00 PM to 6:00 PM in Shenzhen.
The sweet spot is 8:00 AM to 11:00 AM Oslo time, matching 3:00 PM to 6:00 PM in Shenzhen. Shenzhen is 7 hours ahead of Oslo. That leaves about 3 hours of common time — enough for a meeting or two, so use it deliberately. Heads up: because Oslo changes its clocks and Shenzhen doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
