Springtime is right around the corner, as the first day of the season is on Thursday. The first day of spring represents the vernal equinox in the Northern Hemisphere, an astronomical event that occurs when the sun aligns with the Earth’s equator.

On the contrary, in the Southern Hemisphere, the upcoming equinox is known as the autumnal equinox, as it represents the start of fall. During this time, the Southern Hemisphere begins to tilt away from the sun, resulting in cooler weather and shorter days.

The equinox that occurs during the Northern Hemisphere’s spring is called a vernal equinox, while the event that occurs during the Northern Hemisphere’s fall is called an autumnal equinox.
