Anchorage is 12 hours behind Doha
There is no standard 8-to-6 overlap. Someone joins early or late.
Doha and Anchorage have no natural overlap. The 12-hour gap is simply too large for regular working hours to meet. Treat the handoff like a relay — Anchorage wraps up and leaves notes for Doha to pick up as their day begins. A quick caveat — Anchorage's clocks move for daylight saving and Doha's don't, so the times here are right for only part of the year.
