Different areas have different definitions for winter, spring, summer and fall. I go by the definition that the seasons start on the solstices and the equinoxes. In England, as well as the rest of the northern hemisphere, September is the month in which summer ends and fall begins, and October and November are during fall.
The Autumnal equinox. It comes on September 22nd.
because the earth is tilted 23.5 degrees towards the north star, so we have two equinoxes in the spring and fall
The first date of the spring equinox is March 20th
Two equinoxes (from the word 'equal') occur each year: one in the Spring, called the vernal equinox from a word for green-ness, and also the autumnal equinox in the Fall. On the day and hour of the equinoxes, days and nights are the same length of time.
During the equinoxes, when the Sun is at its highest, it will be at a distance from the zenith which is the same as your geographical latitude, but in the opposite direction. For example, if you live 50 degrees north of the equator, the Sun will be 50 degrees south of the zenith at noon.
They begin at the vernal and autumnal equinoxes
At the Equator at the two Equinoxes, Spring and Fall.
What are spring and fall equinoxes
There are two equinoxes (i.e. vernal/spring and autumnal/fall) every year.
Not always. The sun is directly overhead at the equator at the spring and fall equinoxes.

The Spring and Fall Equinoxes are the first days of Spring and Fall. In the southern hemisphere, this is not the case. The Spring equinox occurs around the 21st or 22nd of September, not the first day of Spring, which is September 1. The Autumn equinox occurs around the 21st or 22nd of March, not the first day of Autumn, which is March 1.
Because the Earth is going around the sun every 365-366 days. The equinoxes create the seasons such as spring, summer, fall, and winter. Each equinox is a place on the circle of the Earths path.
The Autumnal equinox. It comes on September 22nd.
One day in spring and another in fall. They're called "equinoxes".
