Best overlap: 9:00 AM to 6:00 PM in Amsterdam is 8:00 AM to 5:00 PM in Casablanca.
Book within 9:00 AM to 6:00 PM Amsterdam time (8:00 AM to 5:00 PM in Casablanca) and both teams will be at work. The overlap is wide at 9 hours, so you can protect mornings for deep work and still find plenty of meeting time. For part of the year the maths changes: Amsterdam observes daylight saving, Casablanca does not, shifting the overlap by an hour.
