Reykjavik is 1 hour behind Stockholm
Best overlap: 9:00 AM to 6:00 PM in Stockholm is 8:00 AM to 5:00 PM in Reykjavik.
Both offices are open during 9:00 AM to 6:00 PM Stockholm time, which is 8:00 AM to 5:00 PM in Reykjavik. With 9 hours in common, treat scheduling almost as if the two cities were in the same region. Because only Stockholm changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Stockholm enters or leaves daylight saving.
