Addis Ababa 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 Addis Ababa.
Both teams are at their desks between 8:00 AM to 5:00 PM in Oslo and 9:00 AM to 6:00 PM in Addis Ababa. 9 hours of shared hours is more than enough — slot meetings wherever they're most convenient for the people involved. One seasonal catch: Oslo springs forward and falls back, but Addis Ababa doesn't, so the gap changes by an hour for several months of the year.
