The resignation of Pope Benedict XVI occurred on 28 February 2013 at 20:00 (8:00 PM) CET (19:00 UTC). The resignation was first announced on the morning of 11 February 2013 by the Vatican.Benedict XVI's decision to step down as leader of the Catholic Church made him the first pope to relinquish the office since Gregory XII in 1415 (who did so in order to end the Western Schism), and the first to do so on his own initiative since Celestine V in 1294. The move was unexpected, given that popes in the modern era have held the position from election until death. The Pope stated that the reason for his decision was his declining health due to old age.The conclave to select his successor began on 12 March 2013 and elected Cardinal Jorge Mario Bergoglio, Archbishop of Buenos Aires, Argentina, who took the name of Francis.
Benedict announced in February 2013 that, due to his advanced age, he would step down. At the age of 85 years and 318 days on the effective date of his retirement, he was the fourth-oldest person to hold the office of pope.
He announced his intention to resign in Latin at the Apostolic Palace in the Sala del Concistoro, at an early morning gathering on 11 February 2013, which was the World Day of the Sick, a Vatican holy day. The gathering was to announce the date of the canonisation of 800 Catholic martyrs,Antonio Primaldo and companions, as well as the Latin American nuns Laura Montoya Upegui and Maria Guadalupe Garcia Zavala. At the ceremony, known as the "Consistory for the canonization of the martyrs of Otranto", he told those present he had made "a decision of great importance for the life of the church". In a statement, Benedict cited his deteriorating strength due to old age and the physical and mental demands of the papacy. He also declared that he would continue to serve the church "through a life dedicated to prayer".
