Effective Date of Resignation
Pope Benedict XVI's resignation became effective on February 28, 2013. He departed from the Vatican and moved to the papal summer residence, Castel Gandolfo, temporarily before settling in a monastery within the Vatican City. His resignation marked the end of his eight-year papacy and began the period known as the Sede Vacante, during which the Church prepared for the upcoming conclave. Benedict XVI assumed the title of Pope Emeritus following his retirement.
