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.
The latitude of the tangent rays in the Northern Hemisphere on June 21st is approximately 23.5 degrees north, which is known as the Tropic of Cancer. This is the northernmost point where the sun's rays are directly overhead during the summer solstice.
There is no time between these. On the day before the autumnal equinox, the sun is directly overhead in the northern hemisphere (at a latitude just north of the equator). The following day, it is directly overhead in the southern hemisphere (just south of the equator). The sun goes from being overhead in the northern hemisphere to the southern hemisphere instantaneously, the change happening at the autumnal equinox.
latitude of the observer.
On December 21, the rays of the sun strike directly on the Tropic of Capricorn, at approximately 23.5 degrees south latitude. This marks the Winter Solstice in the Northern Hemisphere and the Summer Solstice in the Southern Hemisphere.
Northern-hemisphere Winter begins when the sun reaches its farthest positionsouth, on or about December 22, appearing overhead on the Tropic of Capricornat about 231/2°south latitude.Southern-hemisphere Winter begins when the sun reaches its farthest positionnorth, on or about June 21, appearing overhead on the Tropic of Cancer at about231/2° north latitude.
Alaska is the northernmost state of the U. S. Its northernmost point is along 71° 2' to 71° 5' north latitude.
The northern hemisphere does not experience winter when the Earth is farthest from the sun.The cause of the seasons is the Earth's axial tilt, which is independent of the apsides of Earth's orbit, known as aphelion and perihelion.When Earth is farthest from the sun, it is at aphelion. Aphelion currently occurs in July, which is the Northern Hemisphere's summer.

Polaris can be used to determine latitude in the northern hemisphere as it is directly overhead from the north geographic pole. The sun can be used for the same purpose if proper tables are available.

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.
The most northern line of latitude is the Arctic Circle, which is at approximately 66.5 degrees north latitude.
