This phenomenon occurs because the Earth tilts away from the sun, and this is the day where the extent of that phenomenon is shortest: one 24-hour period.
There are zero hours of sunlight at the Antarctic Circle on June 21: the sun does not cross the horizon.
One hundred percent of the Antarctic experiences no daylight for the 24-hour period labeled as June 21: there is no sunrise that day.
At the Antarctic Circle, there are 24 hours of daylight on December 21.

Zero.
It depends on where you are and what season it is. If you are at the equator then there is 12 hours of daylight and 12 hours of night. If you are above the arctic circle then during the winter there is 24 hours of darkness each day, this will occur on Dec. 21st. If you are further above the arctic circle the darkness can last for months. During the summer there will be 24 hours of daylight on June 21st, and again this can last for months if you are very far north. The same is true for the South pole as well.
on December 21st there's 0 hours on June 21st there's 24 hours
24 hours
It's around June 21st or 22nd.
During the summer months, Hammerfest experiences the phenomenon of the Midnight Sun, where the sun does not set for about 2 months. In contrast, during the winter months, the city has polar nights where the sun does not rise for about 2 months.
That's the summer solstice, when areas north of the Arctic Circle will have 24 hours of daylight.
March 20th or 21st
Svalbard is one of the northernmost places on the planet, being above the Arctic Circle. Since it is in the Northern Hemisphere, it experiences winter from December to March. For a part of winter, it is night for twenty-four hours a day north of the Arctic Circle. This has to do with the position of the Sun and the tilt of the Earth. This phenomena is known as polar night, and occurs in the Antarctic Circle during its winter months as well.
At both poles, beyond about 66 degrees of latitude, there is at least one 24-hour period without a sunset/ sunrise, annually. All of Antarctica lies beyond 66 degrees S, so the periods can be days, weeks or months without a sunset.. Predictably, everywhere on Antarctica experiences no sunset on mid-summer's day, which is December 21.
no any country in the world there have no night There is nowhere on Earth that never has night time whatsoever, when the Northern hemisphere tilts towards the sun, areas above a latitude of 66.5 degrees N (more commonly referred to as the Arctic Circle) experience several days without an intervening 'night' in between. However, when the Northern Hemisphere tilts away from the sun in winter, the same areas above the Arctic Circle experience 24 hours of darkness for several days!
December 21st
Yes. The closer to the N. Pole you live, the shorter the night. In Fairbanks, we get about 4 hours of darkness around June 21st. In Anchorage, the night is longer. After Jun 21st, the night gradually gets longer again till Dec. 21st, then starts gettting shorter again.
