How are the March and September equinoxes the same in terms of Earth’s rotation axis?
According to the wikipedia: an equinox occurs twice a year (around 20 March and 22 September), when the tilt of the Earth’s axis is inclined neither away from nor towards the Sun, the center of the Sun being in the same plane as the Earth’s equator.
Why is the fall equinox not on the 21st?
Most years, this happens on either Sept. However, every once in a while, the autumn equinox can occur on Sept. 21 or 24. This happens because the length of a calendar year (365 days) is not equal to the time it takes for Earth to travel around the sun (365.25 days).
What is unique about the spring and autumn equinoxes?
The spring and autumn equinoxes occur around March and September 21. These are special points in the Earth’s orbit when the Sun appears directly above the Earth’s equator. Day and night are nearly the same length, about 12 hours.

On Earth, there are two equinoxes every year: one around March 21 and another around September 22. Sometimes, the equinoxes are nicknamed the “vernal equinox” (spring equinox) and the “autumnal equinox” (fall equinox), although these have different dates in the Northern and Southern Hemispheres.
What are the different equinoxes?
There are only two types of equinoxes. The March and September equinoxes each have their own names. In the Northern Hemisphere, the March equinox is called the vernal equinox, while in September, it is called the autumnal equinox. In the Southern Hemisphere, the names are the opposite because the seasons are switched.
What is the September equinox and when does it occur?
The September equinox occurs the moment the Sun crosses the celestial Equator – the imaginary line in the sky above Earth’s Equator – from north to south. This happens either on September 22, 23, or 24 every year. Earth orbits the Sun at a slant.
What is the difference between the spring equinox and the autumn equinox?
The Autumn Equinox is the first day of the autumn season and occurs when the sun passes the equator moving from the northern to the southern hemisphere. The Spring Equinox is the first day of spring season and occurs when the sun passes the equator moving from the southern to the northern hemisphere.
What are the equinoxes of the northern hemisphere?
So, in the Northern Hemisphere you have: Vernal equinox (about March 21): day and night of equal length, marking the start of spring. Summer solstice (June 20 or 21): longest day of the year, marking the start of summer. Autumnal equinox (about September 23): day and night of equal length, marking the start of autumn.

There also would be no need to mark equinoxes or solstices. The two solstices happen in June (20 or 21) and December (21 or 22). These are the days when the Sun’s path in the sky is the farthest north or south from the Equator.
