Liturgy
The Sacred Paschal Triduum
Season of the liturgical year
The three holiest days of the liturgical year: from the Mass of the Lord's Supper on Holy Thursday through Easter Vespers on Easter Sunday.
The Triduum is one continuous liturgy celebrated over three days: the Evening Mass of the Lord's Supper (Holy Thursday), the Celebration of the Lord's Passion (Good Friday), and the Easter Vigil (Holy Saturday night). The high point of the entire liturgical year.
