Lent is the Christian season of preparation before Easter. In Western Christianity, Ash Wednesday marks the first day, or the start of the season of Lent, which begins 40 days prior to Easter (Sundays are not included in the count).
Lent is a time when many Christians prepare for Easter by observing a period of fasting, repentance, moderation and spiritual discipline. The purpose is to set aside time for reflection on Jesus Christ - his suffering and his sacrifice, his life, death, burial and resurrection.
Not all Christian churches observe Lent. Lent is mostly observed by the Lutheran, Methodist, Presbyterian and Anglican denominations, and also by Roman Catholics. Eastern Orthodox churches observe Lent or Great Lent, during the 6 weeks or 40 days preceding Palm Sunday with fasting continuing during the Holy Week of Orthodox Easter. Lent for Eastern Orthodox churches begins on Monday (called Clean Monday) and Ash Wednesday is not observed.
The Bible does not mention the custom of Lent, however, the practice of repentance and mourning in ashes is found in 2 Samuel 13:19; Esther 4:1; Job 2:8; Daniel 9:3; and Matthew 11:21.
