Portland is 12 hours behind Abu Dhabi
There is no standard 8-to-6 overlap. Someone joins early or late.
When Abu Dhabi starts work, Portland is already winding down or offline — the 12-hour gap leaves no shared window. Default to async and only schedule live time when it genuinely needs a conversation — then make it count. Note that Portland follows daylight saving while Abu Dhabi stays put, so the times above drift by an hour seasonally.
