Vancouver is 7 hours behind Reykjavik
Best overlap: 3:00 PM to 6:00 PM in Reykjavik is 8:00 AM to 11:00 AM in Vancouver.
For the smoothest call, aim inside 3:00 PM to 6:00 PM in Reykjavik, i.e. 8:00 AM to 11:00 AM in Vancouver. Vancouver is 7 hours behind Reykjavik, so the practical overlap is about 3 hours — generous enough for meetings, tight enough to be worth booking ahead. Daylight saving complicates things slightly: Vancouver observes it, Reykjavik doesn't, so the difference flexes by an hour part of the year.
