Addis Ababa is 11 hours ahead of Portland
There is no standard 8-to-6 overlap. Someone joins early or late.
The 11-hour difference means Portland and Addis Ababa miss each other entirely during regular office hours. Where you can, lean on async updates and save live calls for when one team is happy to start early or stay late. Seasonal note: Portland uses daylight saving and Addis Ababa doesn't, so double-check the times in your own months — they can move by an hour.
