Best overlap: 11:00 AM to 6:00 PM in Riyadh is 8:00 AM to 3:00 PM in Edinburgh.
Plan around 11:00 AM to 6:00 PM in Riyadh, which is 8:00 AM to 3:00 PM in Edinburgh, to catch everyone during office hours. The overlap is wide at 7 hours, so you can protect mornings for deep work and still find plenty of meeting time. Daylight saving complicates things slightly: Edinburgh observes it, Riyadh doesn't, so the difference flexes by an hour part of the year.
