Shanghai is 6 hours ahead of Bucharest
Best overlap: 8:00 AM to 12:00 PM in Bucharest is 2:00 PM to 6:00 PM in Shanghai.
Both teams are at their desks between 8:00 AM to 12:00 PM in Bucharest and 2:00 PM to 6:00 PM in Shanghai. Shanghai is 6 hours ahead of Bucharest, leaving about 4 hours of shared hours — plan recurring calls early in that window to leave buffer. 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.
