Midnight Sun

Midnight sun is a period of daylight which lasts for more than 24 hours. It occurs during the summer inside of the Arctic and Antarctic circles. At the edge of the Arctic circle, the sun doesn't set between June 12 and July 1. However, this becomes months further north. During the winter, taiga experiences the opposite phenomenon: polar night. This is the lack of daylight for more than 24 hours, but can be extended to include twilight.
