There is no standard 8-to-6 overlap. Someone joins early or late.
Honolulu and Edinburgh sit on opposite ends of the clock — a 10-hour gap leaves no common business hours to work with. Lean on recorded updates, shared docs, and clear handoffs so the 10-hour gap doesn't stall progress between meetings. One seasonal catch: Edinburgh springs forward and falls back, but Honolulu doesn't, so the gap changes by an hour for several months of the year.
