Even though the word equinox means â??equal nightâ?? in Latin, it isn't entirely true that day and night are exactly the same on the equinox all over the world, just almost. The equinox day actually lasts a little longer than 12 hours. However, at the equator, the day and night stay approximately the same length all year round, even if the day will always appear longer than 12 hours, due to refraction.
