The sun is directly over the Tropic of Cancer, latitude 23.5 degrees north of the Equator. This has the most hours of daylight on June 22nd, which is the Summer Solstice in the Northern Hemisphere.
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.
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.
Only the latitudes at 0 and 180 degrees and those at 90 degrees wouldhave the chance of seeing the sun directly over it's head if the earth wastilted on it's axis by 90 degrees.==============================Answer #2:Thgere is no such latitude as "180 degrees".If the Earth's axis were in the ecliptic plane and the Earth rotated "on its side",then each pole would point directly at the sun at one moment each year.In order to follow through the annual saga, let's say that the north pole pointeddirectly at the sun on January 1, just for an example. Then . . .-- On January 1, the sun would be directly overhead at the north Pole. Allnorthern latitudes, from the equator to the north pole, would have 24 hours ofdaylight. All southern latitudes, from the equator to the south pole, would have24 hours of dark.-- From January 1 to the end of March, the sun would move slowly, fromoverhead at the north pole, to overhead at the equator. The length of daylighteverywhere in the northern latitudes, between the equator and the north pole,would gradually decrease, from 24 hours to 12 hours. The length of daylighteverywhere in the southern latitudes, between the equator and the south pole,would gradually increase, from zero to 12 hours. Every northern latitude woudhave the sun directly overhead once during these 3 months. By April 1, everyplace on Earth would have 12 hours of daylight and 12 hours of dark.-- From April 1 to the end of June, the sun would move slowly, from overhead atthe equator, to overhead at the south pole. The length of daylight everywhere inthe northern latitudes, between the equator and the north pole, would graduallydecrease, from 12 hours to zero. The length of daylight everywhere in thesouthern latitudes, between the equator and the south pole, would graduallyincrease, from 12 hours to 24 hours. Every southern latitude woud have the sundirectly overhead once during these 3 months. By July 1, the northern latitudeswould have zero daylight, and the southern latitudes would have 24 hours of it.-- From July 1 to the end of September, the sun would move slowly, fromoverhead at the south pole, to overhead at the equator. The length of daylighteverywhere in the southern latitudes, between the equator and the south pole,would gradually decrease, from 24 hours to 12 hours. The length of daylighteverywhere in the northern latitudes, between the equator and the north pole,would gradually increase, from zero to 12 hours. Every southern latitude woudhave the sun directly overhead once during these 3 months. By October 1, everyplace on Earth would have 12 hours of daylight and 12 hours of dark.-- From October 1 to the end of December, the sun would move slowly, fromoverhead at the equator, to overhead at the north pole. The length of daylighteverywhere in the southern latitudes, between the equator and the north pole,would gradually decrease, from 12 hours to zero. The length of daylighteverywhere in the northern latitudes, between the equator and the north pole,would gradually increase, from 12 hours to 24 hours. Every northern latitudewoud have the sun directly overhead once during these 3 months. By January 1,the southern latitudes would have zero daylight, and the northern latitudeswould have 24 hours of it.Then the whole thing would repeat during the next year.Every latitude on Earth would have the sun directly overhead twice a year, exceptthe poles, where it would be only once a year.Human life on Earth, of course, would not be possible.
That would depend on where in the world you are. If you were at the North Pole there would be 24 hours of daylight, while at the South Pole there would be no daylight. At points in between the two poles the amount of daylight would be different. At the equator the amount of daylight hours would be about 12 hours.
On a solstice, it is only at the equator that the hours of light and dark are equal. At other parts, they would be different with one of the Poles experiencing 24 hours of daylight and the other Pole experiencing no daylight. If it is the June solstice, then it is the North Pole with 24 hours of daylight and the South Pole with none, while it is the opposite in the December solstice. It is at the equinox that the amount of daylight and darkness hours are equal around the world.
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.
The latitude that experiences the largest change in day length throughout the year (typically higher latitudes) would exhibit the greatest decrease in average daily insolation on a graph. This is due to the larger variation in the number of daylight hours between seasons at higher latitudes compared to lower latitudes.
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.

Iceland in the summer
If the tilt of Earth's axis increased by 10 degrees, there would be more extreme seasons at middle latitudes. This would lead to hotter summers and colder winters with more pronounced temperature variations throughout the year. The length of daylight hours would also change, affecting the timing of sunrise and sunset.
The latitudes that are around the equator are the latitudes that usually have the warmest temperatures. Countries and cities around the equator usually experience sunshine all year round.
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.
That would depend on where in the world you are. If you were at the North Pole there would be 24 hours of daylight, while at the South Pole there would be no daylight. At points in between the two poles the amount of daylight would be different. At the equator the amount of daylight hours would be about 12 hours.
Utah would have the greatest number of daylight hours per day in June. This is because June is the month with the longest daylight hours due to the summer solstice, when the Northern Hemisphere is tilted closest to the sun.
July-June has the longest day of the year,but it has only 30 days. So I would say July has the most hours of daylight.
I presume you mean 'How many hours of daylight.' That would depend on which particular place you mean. In southern Britain you might get 6 hours, in North Cape, Norway, you would not really get any daylight at all.
