Explain simply why before Easter Sunday is the correct answer to: Passage: Lent (Latin: Quadragesima: Fortieth) is a solemn religious observance in the Christian liturgical calendar that begins on Ash Wednesday and ends approximately six weeks later, before Easter Sunday. The purpose of Lent is the preparation of the believer for Easter through prayer, doing penance, mortifying the flesh, repentance of sins, almsgiving, and self-denial. This event is observed in the Anglican, Eastern Orthodox, Oriental Orthodox, Lutheran, Methodist, and Catholic Churches. Some Anabaptist and evangelical churches also observe the Lenten season. Its institutional purpose is heightened in the annual commemoration of Holy Week, marking the death, burial, and resurrection of Jesus, which recalls the tradition and events of the New Testament beginning on Palm Sunday, further climaxing on Jesus' crucifixion on Good Friday, which ultimately culminates in the joyful celebration on Easter Sunday of the Resurrection of Jesus Christ.
