The holiday known as Easter originated as a pagan celebration for the spring equinox which this year was March 19 through the 21st, but it depends on the year and what day the spring equinox falls on. The day was dedicated to observing the resurrection of Jesus Christ, meaning Christ rose from the dead, and it was celebrated around the time of the Jewish Passover. Early Christians who were not Jewish and didn’t participate in Jewish celebrations, would eventually merge their celebrations, recognizing Easter as “Resurrection Day.” The most recognizable symbol of Easter is the Easter Egg, and this symbol goes all the way back to the Ancient Babylonians. They thought that an egg had fallen from heaven and into the Euphrates River, hatching the goddess of fertility, Astarte, meaning Easter. Another popular symbol is the Easter Bunny, representing the spring season and fertility. The bunny originated from the pagan festival dedicated to Eostre representing the goddess associated with the rabbit/hare. The white lily, also known as the Easter lily, associates purity and resurrection. Other flowers associated with Easter are daffodils, crocus, hyacinths, and tulips.
