Best overlap: 9:00 AM to 6:00 PM in Casablanca is 8:00 AM to 5:00 PM in Manchester.
Keep meetings inside 9:00 AM to 6:00 PM in Casablanca — that maps to 8:00 AM to 5:00 PM in Manchester. Manchester is 1 hour behind Casablanca, but you still share a generous 9 hours of overlap, so scheduling is easy and there's room to move a meeting when you need to. Keep an eye on the calendar — Manchester observes daylight saving and Casablanca doesn't, which nudges this window by an hour twice a year.
