When does Norway have 24 hour darkness?

Answer 1

Round the shortest day, 21st of December.
But you have to be in the northern part of the country to get the full dark days.
I am told that even in the south the days will not get real light during the shortest days but I have not been there in winter.
Later in the winter the days will be longer again, in March the length of day and night are almost the same.

Answer 2

Take a globe or a map and look for the arctic circle. It runs north of Mo i Rana and south of Bodo. If you are exactly on this arctic circle, you will not see the sun exactly on December 21st which is the solstice day.
South of the arctic circle there is no 24 hour darkness and north of the circle it depends how far north you are. Narvik would be a good place to stay in darkness (you even have a railway to go there) and Tromso or Hammerfest are even better.
Be aware that "darkness" does not mean it's completely dark. During day time you will have a kind of dawn, the sun just does not creep up over the edge of the horizon. Again - as farer north you are as longer and darker the sun-free time will be.

Answer 3

in the winter months, usually the more north you are in the scandinavian countries, the less daylight you'll have in winter...in summer it's the opposite..sunlight almost 24 hrs a day
