Best overlap: 8:00 AM to 5:00 PM in Reykjavik is 9:00 AM to 6:00 PM in Paris.
For the smoothest call, aim inside 8:00 AM to 5:00 PM in Reykjavik, i.e. 9:00 AM to 6:00 PM in Paris. This is one of the easier pairings: 9 hours of shared time means flexible, low-stress scheduling. For part of the year the maths changes: Paris observes daylight saving, Reykjavik does not, shifting the overlap by an hour.
