September equinox, also known as the first day of autumn in the Northern Hemisphere and the first day of spring in the Southern Hemisphere occurs between September 22 – 24 annually.

The term ‘equinox’ was derived from the Latin word ‘aequus’ which means ‘equal’ or ‘even’ and ‘nox’ meaning night. That being said, this phenomenon allows both the South and North hemispheres to receive equal amounts of sunlight all across the Earth. This phenomenon is caused by the Earth’s tilt, the Northern and Southern Hemispheres trade places in receiving the sun’s light and warmth most directly.

The Earth experiences two equinoxes every year. They are sometimes called ‘autumnal/fall equinox’ and ‘vernal/spring equinox’. Although, those two equinoxes appear on different dates.

Equinox also holds relevance for both astronomers and various communities. Some cultures commemorate harvest festivals in honor of good harvests and abundance of crops. As for the astronomers, the equinox marks the seasonal changes and more celestial observations. At the equinoxes, the sun appears overhead at solar noon from Earth’s equator. The sun is on the celestial equator. The sun rises and sets due east and due west at the equinox. So, the celestial equator intersects due east and due west for everyone around the globe.

The September equinox isn’t just a date in the calendar. Instead, the equinox is proof of the Earth’s tilt and the Sun’s harmony. The shorter days surely bring cooler weather and a great amount of chill awaits in the air. The wild creatures on land are starting to wear their winter coats. It’s officially the season of change.
