In Greenland, since it is close to the pole, the periods of darkness as well as the periods of light last six months, but the days are the same as here; simply, for half the year the sun doesn't set the evening, and for the other half he isn't rising in the morning :)
Oh @_@, but wait, does that mean there will be six months where the sun doesn't set in the evening for the whole day, right? That would be bad for me because I like darkness when sleepingggg
