Equinox means "equal night." The sun is now positioned above the equator. Day and night are very nearly equal in length all over the world. For the Nothern Hemisphere, it is the Spring Equinox because the sun is moving into the North. From now until the Autumnal Equinox, night time will be shorter than day time. Days will continue to become longer and longer until Summer Solstice. (For the Southern Hemisphere, the situation is reversed and Fall begins.) In 2016, March 19th or 20th is the date of spring equinox depending upon location. In the Central Time zone, the exact moment is late night March 19th at 11:30PM CDT.
The name "Ostara" comes from a Teutonic lunar Goddess of fertility, Eostre (also Eastre and Oestara). Her chief symbols are the bunny and the egg. The bunny is for fertility and because ancient worshippers often saw the image of a rabbit in the full moon. The egg represents assurance of renewal, the cosmic egg of creation.
The Norse celebrated the feast of the goddess Iduna, bearer of the magick apples of life, symbol of the light half of the year. Ancient Greeks held Dionysia, a festival of the wine god Dionysos.
The Great Sphinx of Egypt points directly toward the rising Sun on the day of vernal equinox. For those of the Baha'i faith it is the beginning of a new year. Easter, the Christian high holy day celebrating the resurrection of Jesus is near at hand as well.
Through March 25th-- an Olde Calendar fixed date known as "Old Lady Day"-- this is a special time of light-dark balance. The same holds for yin and yang, Earth and Heaven, the forces of feminine and masculine energy.
As we celebrate the rebirth of Nature and the coming lushness of Summer, it is an excellent point in the year to clear out, open up, and begin anything new. This is when to completely revitalize something, to enliven old communications, and to create new connections.
