As the true motion of the Earth in its orbit oscillates around the center of mass of the Terra-Luna binary, there are tiny (up to 1¼ arcsecond) variations of the Sun's apparent ecliptic latitude, which are discussed in section 1.6, that may mean the Sun's centre is not precisely over the equator at the moment of equinox.

On the day of an equinox, daylight and night time are of approximately equal duration all over the planet.

which occurs twice each year, around 20 March and 23 September.

However, the leap year intervals in his calendar were not smooth (400 is not an exact multiple of 97).

This causes the equinox to oscillate by about 53 hours around its mean position.

As a result, the northern and southern hemispheres are equally illuminated.

The word comes from Latin equi or "equal" and nox meaning "night".

In other words, the equinoxes are the only times when the subsolar point is on the equator, meaning that the Sun is exactly overhead at a point on the equatorial line.
