Are there six month days in Norway?

Answer 1

Not really.

In theory, at the north and south poles there are six months of daylight and six months of darkness. In practice, because the Sun is not a point source, what it really amounts to is that near the poles there's a long (but not six months long) period where the sun never rises above the horizon, and a long (but not six months long) period where the sun never fully sets BELOW the horizon, and in between the two are days where the sun does rise (at least partially) and fully set on a 24-hour cycle, but it may never get fully dark or fully light, with the sun just sort of hanging out near the horizon the whole "day".
