The March equinox marks the moment the Sun crosses the celestial equator – the imaginary line in the sky above the Earth’s equator – from south to north. This happens on March 19, 20, or 21 every year.

On the equinox, night and day are nearly the same length – 12 hours – all over the world. This is the reason it’s called an “equinox”, derived from Latin, meaning “equal night.” However, in reality, equinoxes don’t have exactly 12 hours of daylight.

The Earth’s axis is always tilted at an angle of about 23.5° in relation to the ecliptic, the imaginary plane created by the Earth’s path around the Sun. On any other day of the year, the Earth’s axis tilts a little away from or towards the Sun. But on the two equinoxes, the tilt of the Earth’s axis is neither pointing away from nor towards the Sun.
