Abu Dhabi is 12 hours ahead of Portland
There is no standard 8-to-6 overlap. Someone joins early or late.
The 12-hour difference means Portland and Abu Dhabi 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. Don't be caught out by clock changes — Portland observes daylight saving and Abu Dhabi doesn't, so the offset varies by an hour through the year.
