Skinner, it might be too late for us to give Shamrocks for St. Patty's Day

...the ancient rites celebrating the Spring Equinox are most obviously associated with the mysterious Druids and places like Stone Henge, but most ancient races around the world had similar spring festivals to celebrate the rebirth of the year. The Egg, as a symbol of fertility and re-birth, has been associated with these rites from the earliest times.

The Saxon spring festival of Eostre, was named for their goddess of dawn, and when they came to Britain in about the 5th century AD, the festival came with them along with re-birth and fertility rituals involving eggs, chicks and rabbits. When the Saxons converted to Christianity and started to celebrate the death and the resurrection of Christ, it coincided with Eostre, so that's what the early church called the celebration, Eostre or Easter in modern English.
