The length of the day, on the equator, should be about 12 hours, at any time of the year. The exact time of sunset and sunrise may vary: In the center of a time zone, it should rise at 6:00 a.m. and set at 6:00 p.m., on average. However, further east (for example), within the same timezone, the Sun will rise earlier. Also, the equation of time must be considered: The times stated above are only an average.

The Sun's rays only strike the Earth "directly" - i.e., at a 90 degree angle, straight down - at noon on the equinoxes. These are generally March 21 and September 21, although these dates can vary a day either way depending on the cycle of leap years.

And if you want to get REALLY picky, only at the precise moment when the Sun is directly above the equator, which is only true for a few seconds.

equinox

Its called the spring and fall (Autumnal) equinox. It happens twice a year. Usually march 20-21 and September 21-23. The equinox is where the sun is located directly above the equator.

When the earths axis is tilted as far away or as close to the sun as possible, this is called the solstice. This also happens twice a year.

On the Equinoxes, which are generally on March 21 and September 21. (These dates will vary a day either way depending on the cycle of leap years.) It is believed that you can balance an egg PERFECTLY on September 21.Try it!! :)

By The Way: The solstices are on June 21 and December 21.

The sun is directly over a point on the equator twice a year, namely when the earth's poles are
equidistant from the sun, and the sun appears to have reached one of the two points in the sky
known as the "equinoxes".

This takes place once on March 21, and again within a day either way of September 22.

The points where the sun crosses the celestial equator are the equinoxes.

There are two of them. The sun crosses one on March 21 and the other one

around September 21. That's twice in every calendar year.

The equinox. The equinoxes are generally on March 21 and September 21, but this can vary a day or two either way depending on the cycle of leap years. You can look up the precise time of the equinox at the U.S. Naval Observatory's web page "Earth's Seasons" at the link below.

When the sun crosses the equator heading north, on March 21, the northern Hemisphere

marks the beginning of Spring, and the Southern Hemisphere marks the beginning of Autumn.

When the sun crosses the equator heading south, on September 21, the northern Hemisphere

marks the beginning of Autumn, and the southern Hemisphere marks the beginning of Spring.

If you were not reading a newspaper, watching a TV weatherman, or making careful daily

astronomical measurements, you wouldn't notice anything on these occasions.

That happens twice a year, on the days of the Equinoxes. One is almost always

on March 21, and the other is within a day either way of September 21.

Why is it colder at the North Pole in December than at the equator at midnight at the equinoxes - the sun is NEVER directly underfoot at the North Pole but at the equator it is?

The scientific word here for "underfoot" is the "nadir". It's the opposite of the observer's "zenith", which is the overhead point. When the Sun is well below the horizon it really doesn't matter if it's at the nadir. It will not be warming you at the Poles or at the equator. The Sun is overhead at noon on the equator at the equinoxes. It can get very hot on the equator in the daytime then, of course. Thanks to the Earth's atmosphere and oceans a lot of that heat is retained even when the Sun is below the horizon for 12 hours. The fact that the Sun is at the nadir at midnight doesn't matter. Yes, it can get cold at night on the equator, but the North Pole in December is much colder. That's because the North pole doesn't get any sunlight at all for many weeks around December time.

Why is it hot at the Equator all year?

it is hot at the equator since the rays of sun directly fall on the equatorial regions ,that is the sun's rays are parallel on the equator...


Mark the days when the sun appears directly overhead at the Equator?

The Sun, in its seasonal apparent movement across the sky, passes directly over the Equator twice each year, at the March and September equinoxes. At the Equator, the rays of the sun are perpendicular to the surface of the earth on these dates.Places on the Equator experience the quickest rates of sunrise and sunset in the world. They are also the only places in the world where the sun can go directly from the zenithto the nadir and from the nadir to the zenith. Such places also have a theoretical constant 12 hours of day and night throughout the year, though in practice there are variations of a few minutes due to the effects of atmospheric refraction and because sunrise and sunset are measured from the time that the edge of the Sun's disk is on the horizon, rather than the center of the disk.


Is the equator the sun?

Nope


What impact does the equator have on the sun's rays?

They do not. The sun would radiate, as ever, whether or not the equator or even the earth ceased to exist. So the equator has no effect at all.
