Reykjavik is 3 hours ahead of Santiago
Best overlap: 8:00 AM to 3:00 PM in Santiago is 11:00 AM to 6:00 PM in Reykjavik.
The sweet spot is 8:00 AM to 3:00 PM Santiago time, matching 11:00 AM to 6:00 PM in Reykjavik. Scheduling is forgiving here: with 7 hours of overlap, a missed slot just means picking another one the same day. Because only Santiago changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Santiago enters or leaves daylight saving.
