What is the spring equinox?
The spring equinox is a astronomical event particular. The term “equinox” comes from the Latin aequinoctium which translates to “equal night”. Concretely, The equinox corresponds to the time of year when the day and night are of the same length, i.e. 12 hours. From an astronomical point of view, the equinox is due to the perfect alignment of the Earth’s celestial equator with the Sun. The Earth’s axis of rotation is tilted about 23° relative to the plane of its orbit, which causes the Sun to shine directly on the equator and across the entire northern hemisphere.
