How many hours of daylight oin antarctiac?

Answer 1

Depends on your latitude. At the Pole itself, 90oS, you will have no sun at all between the winter-bounding equinoxes. At the Antarctic Circle, at the autumn equinox, you will have only a day or so without sun in the southern winter, and you'll have almost continuous daylight in the southern summer.

BUT in neither case will it be completely dark during the winter, for the moon will still shine!
