The Novendiales period is deeply rooted in Catholic tradition, echoing biblical themes of nine-day mourning and prayer. This practice aligns with the early church’s customs of honoring the deceased as seen in various traditions where extended mourning periods were observed.

During this time, the College of Cardinals gathers in Rome, beginning official preparations for the conclave, the process by which a new pope is elected. In addition to administrative and liturgical duties, these nine days provide an opportunity for the universal church to reflect on the legacy of the departed pontiff, express gratitude for his service and entrust his soul to God’s mercy.

Liturgical Observances
Each day of the Novendiales is marked by special prayers, Masses and liturgical rites, especially in St. Peter’s Basilica and churches around the world. Traditionally, the Requiem Mass (Mass for the Dead) is celebrated daily, offering intercessions for the soul of the pope.

The faithful are encouraged to join in these prayers, whether by attending Mass, reciting the Rosary or engaging in private devotion. In addition, many parishes and dioceses organize special prayer vigils, Eucharistic Adoration and reflections on the pope’s teachings.

The Role of the College of Cardinals
During the Novendiales, the College of Cardinals assumes temporary governance of the Catholic Church. The Camerlengo, the cardinal responsible for overseeing papal affairs during the interregnum (the period between popes), plays a key role in managing the Vatican's day-to-day operations.

The mourning period concludes with the final solemn Mass of the Novendiales, after which preparations for the conclave intensify. The conclave itself, held in the Sistine Chapel, begins shortly after the mourning period ends where cardinals vote to elect the new Bishop of Rome.
