Q. 1. What is the meaning of the words "Easter Triduum?"
A. 1. First of all, to explain the meaning of the word "triduum." A triduum is a period of prayer that lasts three days, usually in preparation for an important feast or in celebration of that feast.
In the Catholic Church, the triduum is the Paschal or Easter Triduum, the time frame that begins with the Mass of the Lord's Supper on the evening of Holy Thursday (Maudy Thursday) and which continues until the start of second vespers (evening prayer) on Easter Sunday.
The Easter Triduum recalls the passion, death, burial, and resurrection of Jesus, as found in the four Gospels of the Holy Bible. It recalls the three days that Jesus spent in the tomb, from Good Friday until Easter Sunday.
The "Easter Triduum" is also known as the "Paschal Triduum," the "Holy Triduum," or the "Three Days."
In the Catholic Church, weddings are prohibited during the Triduum.
