Never.
The Antarctic Circle marks the latitude on planet earth south of which at least one 24-hour period has no sunrise or no sunset.
All latitudes north of the Antarctic Circle experience one sunrise and one sunset each day...until the latitude of the Arctic Circle, where the reverse occurs.
the antarctic circle is experiencing 24 hours of darkness (night)
At the Antarctic Circle per se, the one 24-hour period of no sunset is about September 21.
It does on December 21.
It is one 24 hour period of no sunrise at the Antarctic Circle, when the Arctic Circle experiences the same period of no sunset.
North of the arctic circle, or south of the antarctic circle
North of the Arctic Circle and south of the Antarctic one, the periods of daylight and darkness both vary from zero to six months, during the course of a year.
Arctic north, Antarctic south.
They don't. When it's summer in Australia, the ANTarctic experiences 24-hour daylight for a few months while the ARCTIC, near the NORTH pole, has continual night.
The Antarctic is a landmass: the Arctic is sea ice.
Arctic. Antarctic is the South Pole.
The Antarctic is colder.
The Arctic and the Antarctic
The Arctic surrounds the North Pole and the Antarctic surrounds the South Pole.
The arctic. The Antarctic is on the southern most part of the world.
The Arctic region, anywhere north of the Arctic Circle (approx. latitude 66° 34' N), has the greatest number of daylight hours when it is summer in the Northern Hemisphere. The Antarctic (including almost all of Antarctica), south of the Antarctic Circle (approx. latitude 66° 34' S), has the greatest number of daylight hours when it is summer in the Southern Hemisphere.
