What is the Spring Equinox?

The spring equinox is a distinct astronomical event. The term “equinox” comes from the Latin æquinoctium meaning “equal night.” Essentially, the equinox is the moment of the year when day and night are of equal length, each lasting 12 hours. Astronomically, the equinox occurs due to the perfect alignment of Earth’s celestial equator with the Sun. The Earth’s axis of rotation is tilted by about 23° relative to the plane of its orbit, causing the Sun to shine directly over the equator and across the entire Northern Hemisphere.
