Lent, in Christian tradition, is the period of the liturgical year leading up to Easter. The traditional 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.
Conventionally, it is described as being forty days long, though different denominations calculate the forty days differently. The forty days represent the time that, according to the Bible, Jesus spent in the desert before the beginning of his public ministry, where he endured temptation by Satan.
This practice was virtually universal in Christendom until the Protestant Reformation. Some Protestant churches do not observe Lent, but most, such as Lutherans, Methodists, Presbyterians, Anglicans, and Episcopalians, do.
