equinoxes
March 21st.
Zero latitude -- the equator
Because the equator is closer to the sun. Also, "Not all places along the equator are warm. Some are cold because of elevation. Some places are high up, hence being cold."
yes, because the equator gets a lot of sun:)
Tropical areas near the equator have the warmest climate because the sun's rays are pointed at the middle of the Earth on its axis, called the equator. The directness of the sun's rays obviously causes heat which is why the places around the Earth's equator are warm. :-)

The point in the sky where the sun crosses the celestial equator on its way north is the point called the "Vernal Equinox". The sun reaches that point and passes it on March 21 every year.
The Sun moves from the southern hemisphere to the northern hemisphere around March 20 (or March 21 during leap years) of each year. On this day the sun crosses the true celestial equator - or the line in the sky above the earth's equator - from south to north. It is called Spring Equinox and on this date the day and night are nearly equal 12 hours each all over the world and the earth's axis of rotation is perpendicular to the line connecting the centers the sun crosses the true celestial equator - or the line in the sky above the earth's equator - from south to north of the earth and the sun.

The climate near the equator is warmer than most other places because the sun is closest to the equator.

Sure. At the time the sun reaches the Autumnal Equinox, around September 22 or 23 each year, when the sun crosses the equator, then wherever on the equator it happens to be noon at that moment, the sun is directly overhead there. Also, don't forget about the 22 or 23 September days before that, when the sun is slightly north of the equator, plus the 7 or 8 September days after that, when the sun is slightly south of the equator. There are bunches of places within those latitudes that will have noon-sun overhead, once during the month.
The equinoxes are the two points on the celestial equator there the ecliptic(the sun's apparent annual path through the stars) crosses it.Note that the equinoxes are not events or dates. They are points on the mapof the stars.
