Oslo is 1 hour behind Doha
Best overlap: 9:00 AM to 6:00 PM in Doha is 8:00 AM to 5:00 PM in Oslo.
If you set up a recurring sync, 9:00 AM to 6:00 PM in Doha (8:00 AM to 5:00 PM in Oslo) is the natural home for it. Because you share 9 hours of the workday, there's no need to compromise; book the time that suits the meeting, not the map. Finally, Oslo observes daylight saving and Doha doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
