The region on the earth's surface popularly referred to as the land of midnight sun is the north of the Arctic Circle. This is because at latitudes north of the Arctic Circle (approximately 66.5 degrees north), there are periods of continuous daylight during the summer months. This occurs because the tilt of the Earth's axis means that the sun does not set below the horizon during this time. As a result, areas such as Norway, Sweden, Finland, and parts of Russia, which are located north of the Arctic Circle, experience the "midnight sun" phenomenon during the summer solstice.
