The Porziuncola Indulgence could at first be gained only in the Porziuncola chapel between the afternoon of 1 August and sunset on 2 August. On 5 August 1480 (or 1481), Pope Sixtus IV extended it to all churches of the first and second orders of St. Francis for Franciscans. On 4 July 1622, this privilege was further extended by Gregory XV to all the faithful, who, after confession and the reception of Holy Communion, visited such churches on the appointed day. On 12 October 1622, Gregory XV granted the same privilege to all the churches of the Capuchins. Pope Urban VIII granted it for all churches of the regular Third Order on 13 January 1643, and Clement X for all churches of the Conventuals on 3 October 1670.
