Equinoxes and solstices are a result of two things: Earth’s tilt and its orbit around the Sun. For six months of the year, the North Pole is tilted toward the Sun, and the Sun lies somewhere above the Northern Hemisphere. For the other six months, the South Pole is tilted toward the Sun, and the Sun lies somewhere overhead the Southern Hemisphere.

An equinox in astronomy is the event when the Sun can be observed to be directly above the Earth’s equator, occurring around March 20 and September 22 each year. On these dates, night and day are nearly of the same length and the Sun crosses the celestial equator (i.e., declination 0). More technically, the equinox happens when the Sun is at one of two opposite points on the celestial sphere where the celestial equator and ecliptic intersect. In a wider sense, the equinoxes are the two days each year when the center of the Sun spends an equal amount of time above and below the horizon at every location on Earth. The word equinox derives from the Latin words aequus (equal) and nox (night).
