Abu Dhabi is 13 hours ahead of Anchorage
There is no standard 8-to-6 overlap. Someone joins early or late.
Anchorage and Abu Dhabi live on different parts of the day. With 13 hours between them, standard working hours simply don't meet. Make the most of handoffs — end-of-day in one city becomes start-of-day in the other, so pass work along rather than meeting live. Note that Anchorage follows daylight saving while Abu Dhabi stays put, so the times above drift by an hour seasonally.
