According to Wikipedia, Lent, in some Christian denominations, is the forty-day-long liturgical season of fasting and prayer before Easter. The forty days represent the time Jesus spent in the desert, where according to the Bible he endured temptation by Satan. Different churches calculate the forty days differently.
The purpose of Lent is the preparation of the believer—through prayer, penitence, almsgiving and self-denial—for the annual commemoration during Holy Week of the Death and Resurrection of Jesus, which recalls the events linked to the Passion of Christ and culminates in Easter, the celebration of the Resurrection of Jesus Christ.
In Western Christianity, for the most part, Lent begins on Ash Wednesday and concludes on Holy Saturday. The six Sundays in Lent are not counted among the forty days because each Sunday represents a “mini-Easter”, a celebration of Jesus’ victory over sin and death.
Many Anchorage churches observe Lent with Ash Wednesday services. Ash Wednesday gets its name from the practice of placing ashes on the foreheads of the “faithful” as a sign of repentance.
