The Midnight sun - In the northern 2/3 of Greenland, the sun stays above the horizon for days or even several weeks in the summer. In the remainder, the weeks around the summer solstice June 21, a national holiday see the sun dip below the horizon for only a short while each night, with the sky never getting truly dark. Of course the reverse is true in the winter.
