Geneva is 2 hours behind Addis Ababa
Best overlap: 10:00 AM to 6:00 PM in Addis Ababa is 8:00 AM to 4:00 PM in Geneva.
Keep meetings inside 10:00 AM to 6:00 PM in Addis Ababa — that maps to 8:00 AM to 4:00 PM in Geneva. Because you share 8 hours of the workday, there's no need to compromise; book the time that suits the meeting, not the map. Finally, Geneva observes daylight saving and Addis Ababa doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
