Answer: The Extraordinary Jubilee of Mercy was a Roman Catholic period of prayer held from 8 December 2015, the Solemnity of the Immaculate Conception, to 20 November 2016, the Feast of Christ the King. Like previous jubilees, it was seen by the Church as a period for remission of sins and universal pardon focusing particularly on God's forgiveness and mercy. It was an extraordinary Jubilee because it had not been predetermined long before; ordinary jubilees are usually celebrated every 25 years.

The 2016 Jubilee was first announced by Pope Francis on 13 March 2015. It was declared in the pope's April 2015 papal bull of formal announcement or proclamation Misericordiae Vultus (Latin for "The Face of Mercy"). It is the 27th holy year in history, following the ordinary 2000 Jubilee during John Paul II's papacy. The opening day was also the 50th anniversary of the closing of the Second Vatican Council.
