The length of a papal conclave is not fixed and can vary widely. There is no formal time limit; the conclave continues until a candidate receives a two- thirds plus one majority vote from the cardinal electors

. Typical Duration:

• In modern times, conclaves usually last between two to three days. For example, Pope Francis was elected in 2013 after two days and five ballots, and Pope Benedict XVI was elected in 2005 after two days and four ballots

• If no pope is elected after three days of voting, the cardinals take a day off for prayer and discussion before resuming voting. This pause is designed to help reach consensus

Historical Extremes:

• The longest conclave in history lasted nearly three years (1,006 days) in the 13th century, which led to reforms establishing the conclave system itself

• The longest conclave in the last 200 years lasted 51 days in 1831

• Most conclaves in the last two centuries have lasted less than a week, with the average being around three days

Summary:

• The 2025 conclave began on May 7 and is expected to last a few days, likely two to three, based on recent precedent.
• Voting occurs up to four times a day after the first day.
• The conclave will only end once a candidate secures the required two-thirds majority

In short, while the conclave could theoretically last indefinitely, recent conclaves have typically concluded within two to three days, with procedures in place to encourage a timely decision.
