This is a great addition. above the Arctic Circle, having visited there in late May a few years ago, you can experience the everlasting daylight phenomenon. Of course, everlasting night in the winter if you are so inclined. This year Sunlight all day from 18 May to 26 Jul 2024, The Sunrise and Sunset website below is useful. Hopefully, this will roll over to the summer schedule next year, noted it doesn't start until Dec 24, which is a shame.
