The further north you move, the longer daylight lasts. North of the Arctic Circle, the sun never sets in the summer and you have the sun shining even at midnight.
You get to a point where you get one sunrise and one sunset per year. The six months of daylight is none too bright as the sun is just barely above the horizon. It tracks all the way round the horizon back to where it started every 24 hours. Once it drops below the horizon it gets dark and stays that way for 6 months. When it's dark at the north pole, the south pole has 24 hours of daylight and vice versa.
