We are about to leave Lent and enter the liturgical season known as “Triduum.”
What is this season, and why is it does the Church say that it is “the culmination of the entire liturgical year”?
Here are 6 things you need to know.
1. What does “Triduum” mean?
It comes from Latin roots that mean, essentially, “the three days” or “period of three days” (tri- = three, -dies = days).
Today it refers to the liturgical season that follows Lent and precedes the Easter season.
According to the main document governing the celebrations connected with Easter, Paschales Solemnitatis:
38. . . . This time is called “the triduum of the crucified, buried and risen”; it is also called the “Easter Triduum” because during it is celebrated the Paschal Mystery, that is, the passing of the Lord from this world to his Father.
2. When does Triduum begin and end?
According to the General Norms for the Liturgical Year and the Calendar:
19. The Easter triduum begins with the evening Mass of the Lord’s Supper, reaches its high point in the Easter Vigil, and closes with evening prayer on Easter Sunday.
This means that Triduum thus runs from the evening of Holy Thursday to the evening of Easter Sunday.
It thus includes three full days, though since the season doesn’t begin at midnight, these three days are distributed as follows:
- The last part of Holy Thursday
- Good Friday
- Holy Saturday
- The first part of Easter Sunday
