Reykjavik is 2 hours behind Tel Aviv
Best overlap: 10:00 AM to 6:00 PM in Tel Aviv is 8:00 AM to 4:00 PM in Reykjavik.
The hours that work for both Tel Aviv and Reykjavik are 10:00 AM to 6:00 PM (Tel Aviv) and 8:00 AM to 4:00 PM (Reykjavik). Plenty of room to work with: 8 hours of daily overlap means you can prioritise people's preferences over the clock. One seasonal catch: Tel Aviv springs forward and falls back, but Reykjavik doesn't, so the gap changes by an hour for several months of the year.
