Why are there 13 days of christmas in iceland rather than 12?
Are you interested in Icelandic traditions? Then you will be interested to know about this travel format – nordicsaga.com/independent-norway-tours I have already been on such a tour (both Norway and Iceland). This is completely different from a standard holiday at the beach or ski resort. I got a lot of great experiences there. You can record contacts to contact the agency when the time comes. Good luck!
They get one additional day because they just start celebrating on Eve. That’s it, nothing special. And this is one of the reasons why tourists prefer Iceland during the Christmas holidays. By the way, on this site, you can check some awesome tours to this country. These places are worth visiting not only on Xmas (although, winter is severe on these lands, better stay in cities to my mind).
