Brussels is 12 hours ahead of Honolulu

There is no standard 8-to-6 overlap. Someone joins early or late.

When Honolulu starts work, Brussels 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. Seasonal note: Brussels uses daylight saving and Honolulu doesn't, so double-check the times in your own months — they can move by an hour.
