Doha is 1 hour ahead of Oslo
Best overlap: 8:00 AM to 5:00 PM in Oslo is 9:00 AM to 6:00 PM in Doha.
Plan around 8:00 AM to 5:00 PM in Oslo, which is 9:00 AM to 6:00 PM in Doha, to catch everyone during office hours. Doha is 1 hour ahead of Oslo, but with 9 hours of common ground you can hold morning or afternoon meetings without anyone working odd hours. Don't be caught out by clock changes — Oslo observes daylight saving and Doha doesn't, so the offset varies by an hour through the year.
