Equinox Marks First Day of Season
The vernal equinox, coming this year on March 20, is a day when both daylight and darkness are exactly 12 hours long.
It marks the end of winter and the start of spring in the northern hemisphere, and the end of summer and start of fall in the southern hemisphere.
The Chinese have long celebrated the equinox with feats of egg balancing. An unbroken egg, a symbol of fertility, is said to bring good luck and prosperity for the rest of the season.
Early equinox celebrations in Germanic countries centered around Ostara, the Germanic goddess of spring.
In Persia, the Achaemenid dynasty celebrated this equinox with the festival of Nowruz, meaning “new day.” And in Central America, the Mayans have celebrated this day for centuries with a viewing of the sun as it sets on the El Castillo pyramid in Mexico.
