The two equinoxes occur every spring and autumn.
The "equinoxes" are two points on the map of the stars.
The center of the sun reaches and passes one of them at some moment around
March 21, and the other one at some moment around September 22.
At those moments, the sun is directly overhead some point on the earth's equator, and
every place on earth has roughly equal periods of sun-up and sun-down on that day ...
the only two times in the year when these things happen.
The solstices and equinoxes are points on the map of the stars. Regardless of
where you live, the sun reaches and passes those points at the same times ...
the equinoxes on March 21 and near September 22, and the solstices near June 21
and December 22.
The seasons that begin for you on each of these dates depend on which hemisphere
you live in.

Southern . . . Fall begins
June Solstice:
Northern . . . Summer
Southern . . . Winter
September Equinox:
Northern . . . Fall
Southern . . . Spring

There are two different types of equinoxes; the Vernal Equinox which happens on March 21 or 22. There is also a Autumnal Equinox which happens on September 21, 22 or 23.
Equinoxes are when there are twelve hours of daylight and 12 hours of darkness. The autumnal equinox is on September 21st on average, and the vernal equinox is on March 21st on average. You can tell that the seasons have changed and the equinoxes and solstices have occured because the amount of sunlight changes and temperatures also change. Solstices are when there is either the shortest or longest amount of daylight. The summer solstice is when there is the longest amount of daylight. After the summer solstice, days begin to slowly get shorter until the autumnal equinox. The winter solstice is when there is the shortest amount of daylight. After the winter solstice the days get longer until you reach the vernal equinox.
The Equinox (Vernal & Autumnal) There are only two times of the year when the Earth's axis is tilted neither toward nor away from the sun, resulting in a "nearly" equal amount of daylight and darkness at all latitudes. These events are referred to as Equinoxes
The side of the earth that is closest to the sun is always the sunlit side; this remains true at the equinoxes. An equinox happens at a single moment, and the part of the earth receiving sunlight at these moments will be different from equinox to equinox, because the equinoxes are not in synch with whole days.
both september and march because they both contain equinoxes which is when the sun is at the highest altitude
There are two equinoxes per year, separated by about 6 months. There will never be two equinoxes in one month.
The two equinoxes.
There are two solstices and two equinoxes so the answer is 8.
At the Equator at the two Equinoxes, Spring and Fall.
There are two equinoxes (i.e. vernal/spring and autumnal/fall) every year.

91 and a fraction days. The dividing points are the two solstices and two equinoxes. You can see the precise dates of the equinoxes and solstices on the "Earth's Seasons" web site at the US Naval Observatory, at the link below.
The year has two equinoxes, which are the days on which the night and day are of equal length. They happen when the apparent position of the Sun (on the ecliptic) crosses the Earth's equator.The equinoxes are usually March 21 and September 22, and on those days the Sun has a declination of zero and is overhead at the equator.
At the two equinoxes (about 22 September and 20 March).
They occur around 20 March and 23 September.
