There is one of these 'rings' around the north pole ... called the Arctic Circle ... and another one around
the south pole ... called the Antarctic Circle. These circles mark the farthest distance from each pole
that can possibly have 24 hours without a sunrise, and 24 hours without a sunset. Each of them
is located 23.5 degrees (of latitude) away from its pole.
On June 21, the sun doesn't set on the Arctic Circle (the north one), and doesn't rise on the
Antarctic Circle (the south one).
On December 21, there's no sunrise on the Arctic Circle, and no sunset on the Antarctic Circle.
The Tropic of Cancer is a parallel line located at approximately 23.5 degrees north latitude. It marks the northernmost point where the sun appears directly overhead at noon during the summer solstice in the Northern Hemisphere.
The Antarctic Circle is parallel to the Arctic Circle, as they both mark the latitudes at approximately 66.5 degrees north and south, respectively. These circles denote the points where the sun does not set on the summer solstice and does not rise on the winter solstice.
At 50 degrees north latitude, you would experience approximately 16 to 18 hours of daylight on the summer solstice. The further north you go from the equator, the longer the daylight hours during the summer solstice due to the tilt of the Earth's axis.
That is the approximate latitude of the Arctic Circle, which is the set of southernmost points north of which there is no sunrise on the winter solstice and no sunset on the summer solstice.
. . the summer solstice, June 21.
That is the Tropic of Cancer.
In the Southern Hemisphere the summer solstice occurs when the sun is the farthest south.
The Antarctic Circle - the parallel of latitude 66° 33′ south of the equator. It marks the southernmost point at which the sun is visible on the southern winter solstice and the northernmost point at which the midnight sun can be seen on the southern summer solstice.

The line of Latitude that is 66.33 degrees North of the Equator. It is the point at which the sun does not set at Midsummer or rise above the horizon at Midwinter.The Arctic Circle is the parallel of latitude at 66º 33' north of the Equator.This is the most northerly point at which the Sun is visible during the northern winter solstice, and the most southerly point at which the sun can be seen at midnight on the northern summer solstice
At 50 degrees north latitude, you would experience approximately 16 to 18 hours of daylight on the summer solstice. The further north you go from the equator, the longer the daylight hours during the summer solstice due to the tilt of the Earth's axis.
About 23.5 degrees
The latitude lines that mark the summer and winter solstices are the Tropic of Cancer and the Tropic of Capricorn. The Tropic of Cancer, located at approximately 23.5° North latitude, marks the position of the sun during the summer solstice in the Northern Hemisphere. Conversely, the Tropic of Capricorn, at approximately 23.5° South latitude, marks the position of the sun during the winter solstice in the Northern Hemisphere. These latitudes define the limits of the sun's zenith during these solstices.
It can be anything from zero hours to 24 hours, depending on where on Earth you are, and whether you are talking about the summer solstice or the winter solstice. At the summer solstice, the day is between 12-24 hours, depending on your location, and the night is between 0 and 12 hours.
The term for this phenomenon is the summer solstice. It is the longest day of the year and marks the beginning of summer in the Northern Hemisphere.
Summer solstice is an important time for Milton Keynes because Milton Keynes is located at a far northern latitude, therefore there are only a few hours of darkness. The neo-pagans of Milton Keynes hold a summer solstice celebration there.
