Karachi is 14 hours ahead of Anchorage
There is no standard 8-to-6 overlap. Someone joins early or late.
When Anchorage starts work, Karachi is already winding down or offline — the 14-hour gap leaves no shared window. Default to async and only schedule live time when it genuinely needs a conversation — then make it count. Don't be caught out by clock changes — Anchorage observes daylight saving and Karachi doesn't, so the offset varies by an hour through the year.
