   Why do we have equinoxes?

   • The word “equinox” comes from the Latin words aequus meaning equal and nox meaning night. But day and night are not exactly equal length on the equinox.

   The real equality of day and night only happens in places far enough from the equator to have a seasonal difference in day length of at least 7 minutes, actually occurring a few days towards the winter side of each equinox. One result of this is that, at latitudes below ±2.0 degrees, all the days of the year are longer than the nights.
