OSTARA (pronounced O-STAR-ah) is one of the Lesser Sabbats and is usually celebrated on the Vernal or Spring Equinox right around March 20/21 (although because of its origins, may instead be celebrated on the fixed date of March 25). Other names by which this Sabbat may be known are Eostre’s Day, Rite of Eostre, Alban Eilir, Festival of the Trees, and Lady Day. The Christian holiday of Easter is very near this same time and is determined as the first Sunday after the first Full Moon after the Vernal Equinox.
Ostara is a time to celebrate the arrival of Spring, the renewal and rebirth of Nature herself, and the coming lushness of Summer. It is at this time when light and darkness are in balance, yet the light is growing stronger by the day. The forces of masculine and feminine energy, yin and yang, are also in balance at this time.
