Key holidays for Christians include Easter, Lent, Advent, and Christmas, particularly celebrated by Catholics, Pentecost, All Hallows' Eve, and Holy Innovence are celebrated by other non-Catholic Christians. Lent, a special period of 40 days and night before Easter, in which they reflect on their sins, as well as commemorate the time leading up to Jesus' Death and Resurrection.
