Book within 10:00 AM to 6:00 PM Oslo time (8:00 AM to 4:00 PM in Accra) and both teams will be at work. Accra is 2 hours behind Oslo, but you'd hardly notice — 8 hours of shared hours makes this feel like working in neighbouring time zones. Seasonal note: Oslo uses daylight saving and Accra doesn't, so double-check the times in your own months — they can move by an hour.
