This request refers to two separate events: a canonization and the funeral of Pope Francis. I will address each separately.

Canonization

The process of canonization involves several steps 1 2:

1. Servant of God: A Catholic who is believed to have lived a holy life, or who has been martyred, may have their cause for canonization opened 2. The person is then titled a Servant of God 2.
2. Diocesan Inquiry: The local diocese investigates the candidate's life, virtues, and reputation for holiness 3 1.
3. Venerable: If the findings are positive, the case is passed to the Vatican's Congregation for the Causes of Saints 3. If the Congregation deems the person to have lived a life of heroic virtue, the Pope may declare them "Venerable" 4.
4. Beatification: In most cases, a miracle attributed to the intercession of the Venerable is required for beatification 5. The exception is for those who have been martyred. Once the miracle is confirmed, the Pope may declare the individual "Blessed" 5.
5. Canonization: After beatification, another miracle is generally required for canonization 5. Once this miracle is approved, the Pope can canonize the Blessed, declaring them a Saint of the Church 1 6.

Carlo Acutis

The beatification and canonization of Carlo Acutis is specifically mentioned in the references 3 7.

• Acutis's reputation for holiness grew after his death, leading to the creation of an association to promote his cause for beatification 3.
• The diocesan investigation into his life concluded in 2016 3.
• The Congregation for the Causes of Saints validated the investigation in 2017 3.
• Theologians confirmed his heroic virtues in 2018 3.
• A miracle attributed to Carlo Acutis was approved, and Pope Francis decided to convene a Consistory for his canonization 7.

Papal Funeral

The death of the Pope initiates a series of specific procedures 8 9 10:

1. Verification of Death: The Cardinal Camerlengo officially verifies the Pope's death 8. This is done by striking the Pope's forehead three times with a silver mallet and calling him by his baptismal name 8. The Fisherman's Ring and papal seals are broken 8.
2. Notification: The Dean of the College of Cardinals informs all Cardinals and convokes them for the Congregations of the College. News of the Pope's death is also communicated to the Diplomatic Corps and heads of nations 11.
3. Funeral Rites: The Cardinals celebrate funeral rites for the Pope for nine consecutive days, according to the Ordo Exsequiarum Romani Pontificis 8 9.
4. Election of a New Pope: The Cardinal electors meet in the Vatican to participate in a solemn Eucharistic celebration with the Votive Mass Pro Eligendo Papa 10. The election should start fifteen days after the Pope's death, but not later than twenty 10.
5. Conclave: All Cardinals have the right to vote in the conclave, provided they were legitimately appointed, have the use of reason, and are present in person 8. The Cardinals gather in one room (conclave), without partition, and live in common until a new Pope is elected 8.
6. Secrecy: No one is allowed to communicate secretly with the Cardinals from outside 8. Cardinals may not send messages out, whether verbal or written, under pain of excommunication 8.
7. Election Process: The Cardinals proceed to elect a new Pope 8.

Planning Adjustments

Given these details, pilgrims in Rome would need to adjust their plans as follows:

• Canonization: If pilgrims were in Rome for the canonization of Carlo Acutis, they may now be attending a Consistory regarding his canonization 7.
• Papal Funeral: Due to the death of Pope Francis, pilgrims may instead be attending the funeral rites 9. These rites are held for nine consecutive days 9.
• Papal Election: Pilgrims should also be aware that the election of a new Pope will occur within 15 to 20 days after the death of Pope Francis 10.
