Rooted in ancient Christian and Roman customs, the Novendiales is a period of nine consecutive days dedicated to mourning the death of a pope. The practice dates back centuries, mirroring the ancient Roman tradition of a nine-day funeral rite.
According to Church law, while the mourning period begins immediately upon the pope’s death, marking the official start of the “sede vacante,” or papal interregnum, the Novendiales will begin on the day of the pope’s funeral, scheduled for April 26, and will be followed by consecutive days of Masses until May 4.
