What is an Equinox? 

First day of fall

“Equinox” is derived from the Latin words  ‘Aequi’ and ‘Nox.’ The first one means equal, and the latter means "night." It is when the Sun is precisely above the equator, and the Sun's rays fall directly on it.

As a phenomenon of the Fall Equinox, the day and night are of equal duration on that particular day, that is, 12 Hours of the day and 12 Hours of night. 

As fall passes and winter approaches, changes can be observed around everywhere. The temperature seems to cool down, the birds start to migrate, and much more. But most important is the shortening of daytime.

These phenomena are crucial to track, especially for the agricultural industry, as it provides information on when to plant crops.
