What Is the Conclave and When Will It Begin
A conclave is the private gathering of cardinal electors convened to choose a new pope, and its exact opening date depends on when the papacy becomes vacant. The process is governed by the apostolic constitution Universi Dominici Gregis and later amendments, which set the rules for voting, secrecy, and the timeline for starting the conclave. According to the Vatican and canon law, the conclave must begin 15 to 20 days after the papal office is officially vacant, though cardinals can delay the start for practical reasons Vatican official portal.
Public reporting and Vatican statements focus on the sequence of events that follow a vacancy, including the period of mourning, the funeral or rites for the deceased pope, and the formal announcement of the start date. As of the latest public information, no specific opening date for a 2025 conclave has been announced, because the process begins only after the papal see is truly vacant and the College of Cardinals is ready Forbes Vatican coverage.
Who Can Vote and How the Schedule Is Set
Only cardinal electors under the age of 80 may enter the conclave and cast votes, and their number is capped by recent apostolic letters to limit the electorate to a manageable size. The schedule of the conclave, including the day when Mass is celebrated in the morning and the afternoon voting sessions begin, is decided by the cardinals present in the Vatican at the time of the vacancy Vatican official portal.
Logistics such as the preparation of the Domus Sanctae Marthae for the cardinal electors, security arrangements, and communication blackouts are coordinated by the Vatican Prefecture for the Economic Affairs of the Holy See and other offices.

What Signals Precede the Start of the Conclave
The most visible signal that a conclave is imminent is the announcement by the Camerlengo that the papal ring has been destroyed and the office is vacant, followed by the issuance of a formal call for the conclave. In practice, the Vatican communicates the precise date through official channels, and cardinals begin arriving in Rome days in advance to attend spiritual exercises and briefings Vatican official portal.
Financial markets, media outlets, and observers track these steps closely because the outcome can influence global Catholic institutions, diplomatic relations, and public statements on policy issues. The Vatican Bank and other entities operate under heightened transparency protocols during the sede vacante period, and the conclave itself is closed to outsiders, with only limited live coverage permitted Vatican official portal.
