The two days are known as the Equinox. The spring Equinox (typically June 21) is known as the "Vernal Equinox". The fall Equinox (Typically September 21) is known as the "Autumnal Equinox".
The equinox occurs twice a year when day and night are of approximately equal length. The equinox marks the beginning of spring and autumn. During the equinox, the sun crosses the celestial equator, resulting in nearly equal periods of daylight and darkness.
