There is no top of days for a conclave and since 1830 none had lasted more than five days. The one realized to choose the events of Pope Francis has barely needed more than 24 hours to the White Smoking.
The conclaves of the last century have been relatively short and have lasted between two and five days. In 2013, Francisco was chosen on the second day of conclave after five votes: one the first day, two the second day in the morning and two others that same day in the afternoon.
Benedict XVI was also chosen in 2005 after two days of voting, in which four scrutiny were held.
The conclave that John Paul II left in 1978 lasted three days in which there were eight votes. The longest of the last century and a half is that of 1922, when Pius XI was chosen in a conclave that lasted five days, after 14 votes.
The white smoking of the chimney of the Vatican Sistine Chapel announced Thursday at 18.08 hours that the 133 cardinals gathered in the conclave have collected the necessary votes. The chosen one has been Robert F. Prevost and will do it as Leo XIV: he will be the first American Pope.
