The date (near March 21 in the northern hemisphere) when night and day are nearly the same length and Sun crosses the celestial equator (i.e., declination 0) moving northward. In the southern hemisphere, the vernal equinox corresponds to the center of the Sun crossing the celestial equator moving southward and occurs on the date of the northern autumnal equinox. The vernal equinox marks the first day of the season of spring.
If you live south of the equator, this is your Fall Equinox.
Canton is the fellow who updates your astronomy calendar (full moons, equinoxes, etc.) from his laptop in Santa Fe, New Mexico. It’s his birthday today!
The astronomy calendar is an effort of love and no reciprocity is needed or expected, but if you’d like to say thank you for his efforts, then please visit:

Although the Clear Sky Chart shows only 20 to 40% cloud cover, the ClearOutside site predicts over 80% of the sky obscured by clouds. WeatherUnderground says 39 to 70% and AccuWeather says ~90% cloud cover. Other paid weather-guessers predict partly or mostly cloudy and most give a five to fifteen percent chance of measurable precipitation. Not conditions suitable for star gazing.
Clear skies, dang it! Please?
