Easter Sunday is the most important date in the Christian church.In the bible, it is the day when Mary Magdalene found that an empty tomb in the cave in which Jesus had been placed following his death by crucifixion on the previous Friday.It signifies the end of the 40 days of Lent, meaning Christians who gave up something during lent to signify Jesus' time in the wilderness, can indulge themselves again.Easter Sunday is also when church bells will be rung again, having been silent during Lent.
