Many of us as Catholics, we heard about Year A, B, and C very often. This is the same as liturgical year A, B and C, or Cycle A, B and C. Don’t be confused, in some books, you will come across Year I, II, III, it all the same as A,B,and C.
We are sure majority of us don’t understand what Year or Cycles are all about, but today in a very simple way, we are going to explain, first and foremost, these cycles came into being as a result of the Second Vatican Council, to help us Catholics become more familiar with the text of the Bible. And the three-year cycle of the Church is base on three Gospels readings from (synoptic Gospels) Matthew, Mark, and Luke.
We are now in the liturgical Year or Cycle (B). Remember, each first Sunday of Advent, we start a new liturgical year, we move from one cycle (A, B, or C) to the next. Advent, we all know it is a time of preparation (4 weeks) for the Christmas. The Christmas season, we celebrate the birth of Jesus and this continues until the Baptism. This is followed by the first of two periods of Ordinary Time, which continues until Ash Wednesday. Ash Wednesday marks the beginning of the season of Lent, a time of penitence leading to the Paschal Triduum, Triduum is the three days before Easter. That is Holy Thursday, Good Friday and Holy Saturday. Easter Sunday marks the start of the Easter season, This is the period we are right now, the second Sunday of Easter, which continues as a time of celebration until Pentecost Sunday. Pentecost Sunday marks the start of the second period of Ordinary Time, which continues until the Advent season begins again. The next year shall be (Year C). Take a look at a quick Reference:
Year A - 2019-2020, 2022-23
Year B - 2018, 2020-2021, 2023-24
Year C - 2018-19, 2021-22
