Lent is the 40-day period before Easter that begins on Ash Wednesday and ends on Holy Saturday. It is a time of penitential preparation and fasting to commemorate Jesus' fasting in the desert for 40 days. On Ash Wednesday, ashes made from palm branches from the previous year are used to place crosses on people's foreheads, reminding them of their mortality and need for repentance. During Lent, Christians are called to engage in prayer, fasting, and almsgiving. They also participate in acts like Stations of the Cross, Bible reading, and abstaining from meat on Fridays to remember Christ's suffering. The season ultimately prepares believers for Easter through reflection and sacrifice.
