Yes , Most Holidays associated with Christianity are Pagan celebrations that the Church decided to change so that recently converted Pagans would feel more comfortable. Easter is associated with Jesus because he was resurrected three days after his execution , and according to the current calendar , Easter always falls three days after the Spring Equinox. Our current society has regulated it to be the next Sunday after the Spring equinox. Because every thing with God has to fall on a Sunday. Soon Christmas will too.
