The fall equinox (and also the spring equinox) is at a time/day/date in the year when, in all parts of the earth, the length of the day is the same as the length of the night.
Although technically this is not absolutely and precisely so, the general principle of equal hours of sunlight and darkness on that day holds true for all parts of the globe, regardless of latitude or longitude.

Spring equinox occurs around March 20 and Fall equinox occurs around September 22 for the Northern Hemisphere. For the Southern Hemisphere these dates are opposite; the Spring equinox is around September 22 and the Fall equinox occurs around March 20.
The celestial coordinates of the autumnal equinox are 0 hours right ascension and 0 degrees declination. This marks the point at which the sun crosses the celestial equator, and day and night are of equal length.

The fall equinox usually falls on September 22nd or 23rd each year. It marks the beginning of autumn in the Northern Hemisphere when day and night are roughly equal in length.
Autumnal Equinox was 23. September in 1978

Ah, the fall equinox is such a special time when the sun shines directly on the equator. Its declination is zero because it is right over that imaginary line. Nature is always keeping us in balance and harmony. Just visualize that warm sunlight hugging the Earth with love and peace. Stunning! Keep painting those happy little equations, my friend.
During Spring (Vernal Equinox) - March 20th or 21st = Equator During Fall (Fall Equinox) - September 22nd and 23rd = Equator (Yeah, the sun's rays are most direct on the equator during Spring and Fall) especially the days I mentioned above. The Equinox's
The answer is autumnal equinox.
Spring equinox occurs around March 20 and Fall equinox occurs around September 22 for the Northern Hemisphere. For the Southern Hemisphere these dates are opposite; the Spring equinox is around September 22 and the Fall equinox occurs around March 20.
The celestial coordinates of the autumnal equinox are 0 hours right ascension and 0 degrees declination. This marks the point at which the sun crosses the celestial equator, and day and night are of equal length.
In North America, the first day of fall is considered to be on September's equinox. Every year, there is another equinox around March 20.

This only happens on the fall equinox, the dividing line between summer and fall. If you live in the northern hemisphere, this happens on September 21 (plus or minus one day because of the cycle of leap years) and in the southern hemisphere on March 21.
