Doha is 1 hour ahead of Bucharest
Best overlap: 8:00 AM to 5:00 PM in Bucharest is 9:00 AM to 6:00 PM in Doha.
Keep meetings inside 8:00 AM to 5:00 PM in Bucharest — that maps to 9:00 AM to 6:00 PM in Doha. Because you share 9 hours of the workday, there's no need to compromise; book the time that suits the meeting, not the map. Remember that Bucharest shifts for daylight saving and Doha doesn't, so recalculate the overlap after each clock change.
