Last night I went to an interfaith event and we played a Diversity game. We had to answer questions on each other's religion. The question I was given was "Between what times do Jews celebrate the Sathbath?" The answer I gave was between sunset on Friday and sunset on Saturday. The Jews told me that my answer was really close, but infact its half an hour before sunset on Friday and half an hour after sunset on Saturday. Anyway my silly question is
What do orthodox jews do about celebrating the Sathbath if they are inside the Artic circle somewhere like Finland or Sweden where in winter is dark all the time and in summer its light all the time?
