  • There are days/weeks of continuous night even in the example you mentioned, Alaska.
  • In the polar (66.5 North/South - the North/South Pole) zones, there is continuous daylight during the summer months, centered around Jun 21 in the northern hemisphere and Dec 21 in the southern hemisphere. Only in the middle and high polar zones (70 North/South - the North/South Pole) is there continuous darkness during the winter, centered around Dec 21 in the northern hemisphere and June 21 in the south. So Alaska's northern third would have continuous daylight during a part of the spring and summer, and it's northern tip would be totally dark for a short period in winter.
