The Pagan festivals always coincided with the vernal Equinox on the 21st of March every year. Though the Greek were not fully cognizant of why and when spring comes, they believed Eostre must be pleased to ensure that she returns year after year. The festivals were lavish feasts that celebrated the booming of new flowers, the chirping of birds, butterflies, and sunshine and in general the feeling of rejuvenation that is inherent of spring.
