Best overlap: 9:00 AM to 6:00 PM in Paris is 8:00 AM to 5:00 PM in Reykjavik.
For the smoothest call, aim inside 9:00 AM to 6:00 PM in Paris, i.e. 8:00 AM to 5:00 PM in Reykjavik. The overlap is wide at 9 hours, so you can protect mornings for deep work and still find plenty of meeting time. Note that Paris follows daylight saving while Reykjavik stays put, so the times above drift by an hour seasonally.
