Ostara is one of many names for the spring equinox celebrated around the 21st March. The origin of the word may have come from the Germanic Goddess for spring, Eostre. However, this is busy religious time as it is also the time of Easter and Passover. Germanic countries celebrated this time by planting new crops, although it does not seem to be part of the Celtic tradition. Achaemenians, Persians Kings celebrate at the time No Ruz which means “new day”. This is celebration of hope and is still celebrated today and has its roots in Zoroastrianism. In Iran, they celebrate Chahar-Shanbeh Suri just before No Ruz and it is time of purifying of the home, just before the 13 day celebration of No Ruz. The spring equinox is the time of fertility as natures fertility goes mad. The hare then is a symbol of this, due to the ability of the females to get pregnant easily and male hare bouncing about due to sexual frustration. This is also the time for Mitras who is born at the winter solstice and is resurrected at the spring equinox, and leads his followers to the light after death. Mitras was ordered to sacrifice a white bull which he did not want to do but when the knife entered the creature it turned into the moon and Mitras cloak turned into the night sky.
