I mean its not really a phenomenon, it happens every year in the north as the closer you get to the poles of earth the shorter days get during winter and longer during summer. Midnight sun happens before cause of the curvature of the earth plus light spreading, and no sun at all doesnt really happen so much, its more like a very small amount of sunlight for a long time. I dont live that north but it still means the total daylight we get during the winter solstice is about 6 and a half hours, from 8:45 to 15:15.
