Did you know that at the Arctic Circle, the sun does not set for one day each year?

There are two Polar Circles: one in the Southern Hemisphere, where it partially crosses the coastline of Antarctica, and one in the Northern Hemisphere, where it passes through the northern parts of Canada, Scandinavia, and Russia. The exact location of the Polar Circles varies each year. One year it may be further north, and the next year further south. During the solstice, when the sun reaches the Tropic of Cancer or the Tropic of Capricorn and begins to move in the opposite direction (north or south), the sun does not set for one day on the corresponding Polar Circle. If you go further north of the Arctic Circle or further south of the Antarctic Circle, the number of days per year that the sun does not set increases.
