The sun is at the celestial equator, appearing to go Northwards at the vernal equinox and southwards at the autumnal equinox. The word equinox derives from the Latin roots for "equal" and "night" and so, not surprisingly, the night time is the same as day time: 12 hours each.
The sun is passing over the equator an an equinox, and the day length everywhere is 12 hours.

Equinox
The longest day and shortest night occurs on the summer solstice. The shortest day and longest night occurs on the winter solstice. Midway between these points (2x a year) are the equinox, where the day and night are of equal length.
equal day and night
An equinox occurs when the length of the day is equal to the length of the night. Here on Earth, it occurs around March 21 (the Vernal Equinox) and September 21 (the Autumnal Equinox).
At equinox, the Sun rises exactly in the East, and sets exactly in the West. Day and night have approximately (but not exactly) the same length.
In the Spring and Fall equinox, night and day have the same number of hours. Equi = equal.

During the Autumn equinox the length of the day and night are nearly equal. The length of the day on the equinox is approximately twelve hours.
