The Autumnal Equinox in Denver is Tuesday, September 22, 2017 at 7:30 a.m. MDT. So just what is the equinox? There are two equinoxes every year (September and March) when the sun shines directly on the equator and the length of day and night is nearly equal. It occurs the moment the Sun crosses the celestial equator – the imaginary line in the sky above the Earth’s equator – from north to south. This happens either on September 22, 23, or 24 every year.
