The Inuvik Sunrise Festival in Canada's Northwest Territories marks the return of the sun after more than 30 days of polar nights and no official sunrise.
Polar night, a phenomenon in which night lasts more than 24 hours, is caused by the Earth's rotation relative to the position of the Sun. The Earth rotates around a specific axis, which means that there are periods of the year when the Arctic Circle and Antarctic Circle are either completely exposed or obscured from the Sun. Due to its northern location, Inuvik also sees 56 days of 24-hour daylight in the summer.
