Ash Wednesday, a day of fasting, is the first day of Lent in Western Christianity. It occurs 46 days (40 fasting days, if the six Sundays, which are not days of fast, are excluded) before Easter and can fall as early as February 4 or as late as March 10. Ash Wednesday is observed by many Western Christians, including Anglicans, Lutherans, Methodists, Presbyterians, Roman Catholics,[note 1] and some Baptists.
According to the canonical gospels of Matthew, Mark and Luke, Jesus Christ spent 40 days fasting in the desert, where he endured temptation by Satan. Lent originated as a mirroring of this, fasting 40 days as preparation for Easter. Every Sunday was seen as a commemoration of the Sunday of Christ’s resurrection and so as a feast day on which fasting was inappropriate. Accordingly, Christians fasted from Monday to Saturday (six days) during six weeks and from Wednesday to Saturday (four days) in the preceding week, thus making up the number of 40 days. Orthodox Christians do this 40 days in a row.
Ash Wednesday derives its name from the practice of blessing ashes made from palm branches blessed on the previous year’s Palm Sunday, and placing them on the heads of participants to the accompaniment of the words “Repent, and believe in the Gospel” or “Remember that you are dust, and to dust you shall return”.
