Best overlap: 9:00 AM to 6:00 PM in Riyadh is 8:00 AM to 5:00 PM in Amsterdam.
Target 9:00 AM to 6:00 PM in Riyadh, which lands at 8:00 AM to 5:00 PM for the Amsterdam side.

For part of the year the maths changes: Amsterdam observes daylight saving, Riyadh does not, shifting the overlap by an hour.
