Honolulu is 12 hours behind Barcelona

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

Set against a 12-hour difference, Barcelona and Honolulu run their workdays on completely separate schedules. Block a single recurring off-hours slot that both teams agree on, rather than negotiating a new awkward time every week. Don't be caught out by clock changes — Barcelona observes daylight saving and Honolulu doesn't, so the offset varies by an hour through the year.
