The Seasons of the Church
The Advent Season begins the new Church year. This season is based on the four Sundays before Christmas. That means that the last week can be anything from a full week, when Christmas is on a Sunday to one day when it is on a Monday. Near the end of Advent is a period of proximate preparation for the Holy Day that begins on the 17th of December.
The Christmas Season begins with the Vigil of Christmas and runs through the Feast of the Baptism of the Lord, which may fall on the Sunday following Epiphany or may fall the Monday right after. It all depends on which day of the week Christmas falls.
Ordinary Time is a season in two parts. The first part goes from the end of the Christmas Season until the start of Lent. The second goes from after Pentecost until the start of the Advent season in the new liturgical year. The season is called “Ordinary” not because it is, as the dictionary defines, of no special quality or interest; commonplace; unexceptional. It is called Ordinary because its Sundays are defined by ordinal numbers, e.g., 10th Week of Ordinary Time, 27th Week of Ordinary Time. There are 34 Sundays in Ordinary Time, though the 34th is celebrated as Jesus Christ, King of the Universe.
Lent lasts from Ash Wednesday until the Easter Vigil. We all know the song, “These 40 Days of Lent.” However, there are, in fact, 46 days from Ash Wednesday to Easter. This makes me say that the 6 Sundays are not counted as being part of Lent—it is the only way that we have 40 days of Lent. Still, I don’t like to see them considered as “breaks” from the Lent Season. I highly encourage people not to see it as a break from Lenten “give ups” and other practices; Lent should not be the time of looking for loopholes. The last week is known as Holy Week.
The Triduum. The days from the Mass of the Lords Supper on Holy Thursday through Easter Sunday (Holy Thursday, Good Friday, Holy Saturday, Easter Sunday) are known as the Triduum, the Three Days. You ask, “Isn’t that four days? Is four days really three days like God being One and Three?” No, this is not a mystery. These days are counted from evening to evening: Thursday to Friday, (1); Friday to Saturday, (2); Saturday to Sunday (3). While not a season in and of itself crosses the seasons of Lent and Easter, they are important days, the most important, the central days in the entire Church year.
The Easter Season is the 50 days after Easter until Pentecost. There is something appropriate about there being 40 days of penance and preparation, but 50 days of feast and celebration. The Easter Octave is the first week of Easter from Easter Sunday to the Second Sunday of Easter. Note the terminology, Octave of Easter, not after Easter. It is the extension of the celebration of Easter Sunday over eight days. As I like to say, the tomb could not hold Christ, one day cannot hold our celebration of the resurrection!
