Latitudes 'higher' than the Antarctic Circle -- latitude 66° 33′ 39″ -- all the way to 90°, experience at least one day per year with no sunset.
At the South Pole -- 90° -- there is one sunrise per year and one sunset per year. During the six months while there is no sunset, every day has 24 hours of daylight.
In these higher latitudes, the phenomenon of sunrise and sunset is remarkably different from the experience of sunrise/sunset in lower latitudes.
For example, in the six to eight weeks between the first sunrise and the last sunset, in the spring, the sun rises and sets at dramatically different points on the compass. This is at 77°, at McMurdo Station.
The sunset at South Pole takes most of the day, as the sun slips slowly around the horizon until finally, the orb is below the line that separates sky from earth.
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.
December 22 is close to the northern hemisphere's winter solstice (December 21), when the Sun is furthest south. At that date the Sun does not rise above the horizon at all latitudes north of the Arctic Circle (approximately 66.5 degrees north). They therefore have zero hours of daylight.
Mid-latitudes
North of the Antarctic Circle, geographies experience a mix of hours of sunlight and hours of no sunlight. At the Antarctic Circle, there is at least one 24-hour period of no sunrise/ sunset per year. At the Equator, these periods are about 12 hours each.
Those are the "polar" regions.
I'm sure that is the Antarctic Circle.
The Arctic Circle is in the Northern Hemisphere and encompasses the area around the North Pole, while the Antarctic Circle is in the Southern Hemisphere and surrounds the South Pole. The Arctic Circle is predominantly ocean surrounded by land, while the Antarctic Circle is mostly landmass surrounded by ocean. Both circles mark the latitudes where 24 hours of continuous daylight or darkness can occur, depending on the time of year.
"High" latitudes. The equator has a latitude of zero. The area between the Tropic of Cancer (at 23.5 degrees north) and the Tropic of Capricorn (at 23.5 degrees south) are the "tropics" or low latitudes. The "polar regions" are above the Arctic Circle or below the Antarctic Circle, where the latitudes are higher than 66.5 degrees (north or south) are "high". The areas between the tropics and the arctic/antarctic are called "mid-latitudes or "temperate zones".

If you experience 24 hours of daylight in the summer, you would be located in regions north of the Arctic Circle or south of the Antarctic Circle. This phenomenon is known as the midnight sun, where the sun remains visible for the entire 24 hours due to the tilt of the Earth's axis.
The Sun stays up only for latitudes above the Arctic Circle and Antarctic Circle, which is at 66.7 degrees north and south latitudes respectively. So anyplace with a latitude less than 66.7 degrees (in either direction) will never experience the "midnight sun".
In the Arctic Circle and the Antarctic Circle, there are places where the sun does not set for several months during the summer, resulting in continuous daylight.
