Have you ever noticed that the celebration of Easter is not on the same date every year? It can be anywhere between the 22nd of March and 25th of April. The date is set within a week of the first full moon, after 21st of March. It is believed that the holiday was named after the ancient Germanic goddess, Eastre. She was the symbol of the rabbit and the egg; both of these symbols are linked to rebirth and new life.
I noticed there were a few other errors so I also fixed that as well ^^
I hope this helps
