Polar night
Early afternoon in Tromsø. This photo was taken in December.
The polar night is when it stays dark outside for more than twenty four hours. This occurs only inside the polar circles (the northernmost and southernmost areas on Earth).[1] A lot of times It will be a polar night for the winter and the opposite happens in the summer.
