What is Equinox?

Equinox is a celestial event during which, the day and night on the earth is almost the same because the Earth neither shifts away from the sun, nor toward it. The astronomical event occurs twice a year, in March and September, when the sun is right above the Earth's equator.

The Earth’s axis is also rotated at an angle of 23.5 degrees. According to Starwalk:

This means that the Earth’s Northern and Southern Hemispheres receive unequal amounts of sunlight during most of the year. This axial tilt is the reason we have seasons.
