Rome is 1 hour ahead of Reykjavik
Best overlap: 8:00 AM to 5:00 PM in Reykjavik is 9:00 AM to 6:00 PM in Rome.
If you set up a recurring sync, 8:00 AM to 5:00 PM in Reykjavik (9:00 AM to 6:00 PM in Rome) is the natural home for it. Rome is 1 hour ahead of Reykjavik, but the generous 9-hour window means both teams can meet well within their normal day. Finally, Rome observes daylight saving and Reykjavik doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
