24 hours
The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the sun can remain continuously above or below the horizon for 24 hours (at the June solstice and December solsticerespectively).
It is due to the Earth's incline which I think is 24.5 degrees. As the Earth orbits around the Sun, different locations of our planet receive more sunlight, that is why we have seasons. On June 21st, It is the summer solstice, so the Northern Hemisphere receives more sunlight thus it is summer. The Arctic Circle is leaning towards the sun 24 hours so the sun is always present in the horizon. See related link.
The Arctic Circle does not move - it's always at N 66.5 degrees.

You are misinformed, the Sun DOES set in the Arctic Circle.
At the summer solstice, the sun is above the horizon for 24 continuous hours.
Yes there is sunlight in Antarctica. Like the north pole has an Arctic Circle, Antarctica has an Antarctic Circle. Where June 21 has 24 hours of daylight at the Arctic Circle and northward, the south pole at this time has 24 hours of nighttime. Over the next six months this cycle shifts so that on December 21 the south pole has 24 hour sunlight, and the North Pole has 24 hours of nighttime. This is because the earth is tilted on axis by 23.5 degrees. When Earth is on one side of the sun the southern and bottom portion get most of the heat and light, when the Earth has moved half way around the sun the northern and top get most of the heart and sunlight.
