Bucharest is 6 hours behind Shanghai
Best overlap: 2:00 PM to 6:00 PM in Shanghai is 8:00 AM to 12:00 PM in Bucharest.
The hours that work for both Shanghai and Bucharest are 2:00 PM to 6:00 PM (Shanghai) and 8:00 AM to 12:00 PM (Bucharest). Roughly 4 hours of shared hours means scheduling takes a little care — 2:00 PM in Shanghai / 8:00 AM in Bucharest is a safe default. A quick caveat — Bucharest's clocks move for daylight saving and Shanghai's don't, so the times here are right for only part of the year.
