This feast commemorates the visions of Our Lady seen near Fátima in Portugal in 1917 by three shepherd children, Lúcia dos Santos and her cousins Jacinta and Francisco Marto. The visions occurred on 13th day of each month from May to October.
Pope John Paul II was devoted to Our Lady of Fátima and attributed his survival of an assassin’s bullet on 13 May 1981 to her intervention. Jacinta and Francisco Marto, who died in the great Spanish Flu pandemic of 1919-20, were beatified on 13 May 2000.
