Anchorage is 12 hours behind Addis Ababa
There is no standard 8-to-6 overlap. Someone joins early or late.
When Addis Ababa starts work, Anchorage 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. For part of the year the maths changes: Anchorage observes daylight saving, Addis Ababa does not, shifting the overlap by an hour.
