On June 21, the summer solstice, locations between 66.5 degrees North (the Arctic Circle) and 90 degrees North (the North Pole) experience 24 hours of daylight. This phenomenon occurs because the North Pole is tilted towards the Sun during this time, resulting in continuous sunlight for regions within the Arctic Circle. As you move closer to the Pole, the duration of daylight remains constant at 24 hours.
