9. The Vernal Equinox
The first day of the spring season is called the vernal equinox. The vernal equinox is a combination of two Latin words: “vernal”, which translates to “spring”, and “equinox”, which translates to “equal night”. On this day around the world, both day and night are equal, i.e. both are 12 hours. The vernal equinox occurs when the tilt of the Earth’s axis is neither facing away nor facing towards the sun.
