It wasn’t always Easter Sunday
In early Christianity during the second century, the definitions of the dates of Easter were not uniform. The western Roman empire observed lent in the fashion we do today, fasting until the third Sunday of the Paschal Lunar Month, specifically the Sunday after that lunar month’s full moon. However, in the eastern provinces of Rome there was the Quartodeciman, who used the Hebrew Calendar to guide Easter dates. They would determine the end of Lent as Nisan 14 or Passover in the Jewish Faith. This eventually sparked controversy, calls for excommunication, as you can imagine. Eventually this led to the First Council of Nicaea, which established the independence of Christian Lent from the Hebrew Calendar.
Red Easter eggs
Some of the earliest practice of celebrating Easter with eggs was in Mesopotamia where they apparently stained eggs red to symbol the blood of Christ. This is still practice in some Eastern Orthodox churches where the eggs are blessed by a priest.
No chocolate
Technically, in the history of Western Christianity, Easter has strict rules around fasting. During Lent meat, dairy products, eggs and wine were meant to be abstained from. Many still do practice their own forms of fasting during Easter today, but generally people are more lenient on themselves, particular with chocolate. Lucky for Cadbury.
