Saint Patrick's Day, or the Feast of Saint Patrick (Irish: Lá Fhéile Pádraig, "the Day of the Festival of Patrick"), is a cultural and religious celebration occurring annually on 17 March, the death date of the most commonly-recognized patron saint of Ireland, Saint Patrick (c. AD 385–461).
On St Patrick's Day it is customary to wear shamrocks and/or green clothing or accessories (the "wearing of the green"). St Patrick is said to have used the shamrock, a three-leaved plant, to explain the Holy Trinity to the pagan Irish.

The Vernal Equinox
The word equinox is derived from the Latin words meaning “equal night.”
Days and nights are approximately equal everywhere on earth and the Sun rises and sets due east and west.
At the equinoxes, the tilt of Earth relative to the Sun is zero, which means that Earth’s axis neither points toward nor away from the Sun.
According to folklore, you can stand a raw egg on its end on the day of the Vernal Equinox.
