Ash Wednesday is a Christian holy day of prayer and fasting. It is preceded by Shrove Tuesday and falls on the first day of Lent [the six weeks of penitence before Easter]. Ash Wednesday is traditionally observed by Western Christians.

Lent is a solemn religious observance in the Christian liturgical calendar commemorating the 40 days Jesus spent fasting in the desert, according to the Gospels of Matthew, Mark and Luke, before beginning his public ministry, during which he endured temptation by Satan.
