equinoxes
Well that’s simple! The equinoxes are when the Sun is right over the Equator, in between the two Tropics. They occur around March 21st and September 23rd and mark the beginning of spring or autumn. We call the beginning of spring the vernal equinox, while the beginning of autumn is, conveniently, the autumnal equinox.
What receives the direct sunlight on September 21 and March 21?

The autumnal equinox happens on September 22 or 23 and the vernal or spring equinox happens March 21 or 22 in the Northern Hemisphere.
What causes equinox?
An equinox is an event that takes place in Earth’s orbit around the sun. The equinoxes and solstices are caused by Earth’s tilt on its axis and ceaseless motion in orbit. You can think of an equinox as happening on the imaginary dome of our sky, or as an event that happens in Earth’s orbit around the sun.
Is September 21 the last day of summer?

While summer starts and ends at the same moment in time all over the Northern Hemisphere, the date and local time differ from place to place depending on the year and a location’s time zone.
