Lent is a season of forty days, not counting Sundays, which begins on Ash Wednesday, this year it falls on February 22 and ends on Holy Saturday, the day before Easter. The forty days represents the time Jesus spent in the wilderness, enduring the temptation of Satan and preparing to begin his ministry.
Lent is a time of repentance, fasting and preparation for the coming of Easter. It is a time of self-examination and reflection. It is a time we can focus on our relationship with God, grow as disciples and extend ourselves, often choosing to give up something or to volunteer and give of ourselves for others.
Sundays in Lent are not counted in the forty days because each Sunday represents a "mini-Easter." This is why we say"Sunday in Lent" rather than "Sunday of Lent" in the naming of these Sundays. On each Lord's Day in Lent, while Lenten fasts continue, the reverent spirit of Lent is tempered with joyful anticipation of the Resurrection.
