Easter is a Christian holiday that celebrates Jesus' resurrection from the dead. It is preceded by Lent, which lasts 40 days as a remembrance of Jesus' time in the wilderness. During Lent, Christians traditionally give something up, such as chocolate. The week before Easter includes important holy days like Maundy Thursday, commemorating the Last Supper, and Good Friday, when Jesus was crucified. On Easter Sunday, Christians celebrate Jesus' defeat of death with church services, bells, flowers and eggs, a symbol of rebirth.
