Astronomy The Celestial Equator and the Ecliptic are two Great Circle s. As such, they intersect at two points, the Equinox es. When the Sun, which moves along the ecliptic, occupies the point that crosses the equator while heading north, it is the time of the vernal equinox. Due to the Precession Of The Equinoxes , the point of intersection moves completely around the sky in a 25,800-year cycle. This century it is in the southwest portion of Pisces moving slowly toward Aquarius . Solar term In east Asian or period of time when the Sun lies between the Celestial Longitude s of 0° and 15°.

Egg-balancing myth A common Old Wives' Tale regarding the vernal equinox is that this is the one day of the year that eggs can be balanced on their end. Although this myth is untrue (eggs can be balanced on any date with enough patience) and unsound (would it be different in both hemispheres? Why only the instant of vernal equinox? Why not autumnal equinox?) it is often perpetuated in the news. Also, the current Guinness World Record for egg balancing wasn't done on the vernal equinox.
