Lent is a period of fasting, moderation, and self-denial traditionally observed by Catholics and some Protestant denominations. It begins with Ash Wednesday and ends with Easter Sunday. The length of the Lenten fast was established in the 4th century as 46 days (40 days, not counting Sundays). During Lent, participants eat sparingly or give up a particular food or habit. It’s not uncommon for people to give up something they would not normally give up. It’s six weeks of self-discipline.
