Ordinary Time is the portion of the Western Christian liturgical year not part of Advent, Christmas, Lent, or Easter. The Catholic Church divides Ordinary Time into two periods: the weeks between the Baptism of the Lord (in mid-January) and Ash Wednesday, and the longer span from the Monday after Pentecost through the Saturday before Advent. Ordinary Time is marked liturgically by green vestments and focuses on the unfolding of Christ's earthly ministry through the Sunday Gospel readings. The term "ordinary" reflects the Latin ordo (sequence, ranking) rather than the English sense of "unremarkable"; the weeks are ordered by number (the First Sunday in Ordinary Time, the Second, etc.).
