Happy Autumn Equinox everyone <3

In 2021, the autumnal equinox—also called the September equinox or fall equinox—arrives on Wednesday, September 22. This date marks the start of fall in the Northern Hemisphere.

The word “equinox” comes from Latin aequus, meaning “equal,” and nox, “night.” On the equinox, day and night are roughly equal in length.
During the equinox, the Sun crosses what we call the “celestial equator”—an imaginary extension of Earth’s equator line into space.
The equinox occurs precisely when the Sun’s center passes through this line. When the Sun crosses the equator from north to south, this marks the autumnal equinox.
