The subsolar point describes the latitude where the sun’s rays hit the Earth exactly perpendicular to the Earth’s surface. It is where the sun appears directly overhead at noon. The subsolar point appears at the Equator twice a year (during the equinoxes), and migrates north and south across the tropics during the rest of the year.
Full Answer
When is the Sun directly overhead? Since the Earth's rotation axis is tilted 23.5 degrees with respect to its orbital motion around the Sun Save this story for later. Question: When is the Sun directly overhead? (assume you are in the United States of America) Everyday at noon. Answer: For continental U.S. the answer is never.
At the summer solstice, the sun is directly overhead at the Tropic of Cancer (23 degrees north); at the winter solstice, it’s directly overhead at the Tropic of Capricorn (23 degrees south); and it’s that fact that defines those tropics. It is never directly overhead north or south of the tropics. Incomplete question.
The configuration depicted, will happen on the southern hemisphere summer solstice (about December 21st): The only day of the year when the sun passes exactly overhead on the Tropic of Capricorn.
On the summer solstice (June 21ish) Answer: For continental U.S. the answer is never. Since the Earth's rotation axis is tilted 23.5 degrees with respect to its orbital motion around the Sun, one would have to be less than 23.5 degrees above or below the equator to have the Sun pass directly overhead (once per year).
the equatorThe sun is directly overhead at noon on the equator on the first day of spring (vernal equinox) and on the first day of fall (autumnal equinox). The sun is directly overhead at noon on the first day of summer at a point 23.5 degrees north of the equator (called the Tropic of Cancer).
The sun is directly overhead at "high-noon" on the equator twice per year, at the two equinoxes. Spring (or Vernal) Equinox is usually March 20, and Fall (or Autumnal) equinox is usually September 22.
The sun is directly overhead at noon. At the Decrmber Solstice, the sun is always to the south, and never quites get directly overhead. The equator has 12 hours of sunlight every day of the year.

Answer: Overhead sun is a phrase which means for noon when Sun stands just above our head. Hope this answer is helpful.
Once or twice each year, people who live at lower latitudes (within 23.5 degrees of the equator) can see the sun reach the zenith, an imaginary point directly overhead. (If you poked a pencil straight into the ground when the sun was at its zenith, it would make no shadow at all.)
Having the sun directly overhead can happen only between the Cancer and Capricorn tropics. That is, only the places between 23.5° of latitude north and 23.5° of latitude south. On the Cancer tropic (23.5° latitude north) it will happen once every year, on the day of the northern hemisphere solstice (about June 21st).
That highest point is called solar noon. It's the moment when the sun crosses our local meridian, or line of longitude, and appears due south in the sky. At any location on Earth, the time of solar noon can differ from average by as much as 30 minutes throughout the year.
Answer: For continental U.S. the answer is never. Since the Earth's rotation axis is tilted 23.5 degrees with respect to its orbital motion around the Sun, one would have to be less than 23.5 degrees above or below the equator to have the Sun pass directly overhead (once per year).
The sun's apparent movement towards north and south of the equator is within two tropics. All the places located within the tropics have overhead sun twice a year. Both Ahmedabad and Kolkata lie to the south of the Tropic of Cancer. That is why these two stations see the noon sun overhead twice a year.
Solution. The sun is overhead on a line of longitude only once in a day.
the Tropic of CancerThe seasons on Earth are caused by the 23.5° tilt of the axis of rotation. The summer begins on or about June 21, when the Sun is directly overhead at local noon on the Tropic of Cancer (23.5°N latitude). This is the Summer Solstice. Solstice means “Sun stands still” in Latin.
Common Answers: Everyday at noon. On the summer solstice (June 21ish) Answer: For continental U.S. the answer is never. Since the Earth's rotation axis is tilted 23.5 degrees with respect to its orbital motion around the Sun, one would have to be less than 23.5 degrees above or below the equator to have the Sun pass directly overhead ...

For any other given place between the tropics, it will also happen twice every year. On the days when the Declination of the sun (a coordinate in the sky analogous to latitude on the Earth), matches the latitude of the place. Various formulas to calculate the declination to various precision can be found at Wikipedia.
That is, only the places between 23.5° of latitude north and 23.5° of latitude south. On the Cancer tropic (23.5° latitude north) it will happen once every year, on the day of the northern hemisphere solstice (about June 21st).
