Spring Equinox 2025. In fact the word equinox is taken from the latin aequus (equal) and nox (night) or equal night. Equinox literally means “equal night.” on the spring equinox, the sun is positioned directly over the equator, which makes day and night equal in length all over the world, only on the equinox.
It is a time for balance. Spring will last from march 20 until june 21, when summer officially starts in 2025.
