The Hour of Grace for the World is celebrated from 12.00 pm to 1.00 pm at the solemnity of the Immaculate Conception of the Blessed Virgin Mary. It is connected with the revelation of Mary on December 8th, 1947, in Montichiari, Italy, where She said: It is my wish that every year, on 8th December, at noon, the Hour of Grace for the World be celebrated. Many divine and bodily graces will be received through this devotion. … This Hour of Grace will produce great and numerous conversions. Hardened and cold hearts resembling this marble will be touched by divine Grace, and they will become faithful to Our Lord in loyal love. … it is my wish that the Hour of Grace for the World be made known and spread throughout the world. … Soon one will recognize the greatness of this Hour of Grace. … If anyone is unable to visit his church, yet will pray at noon at home. At the Shrine of Divine Mercy in Krakow-Łagiewniki, the Hour of Grace is traditionally practiced in the chapel with the miracle-famous image of Merciful Jesus and the tomb of St. Faustina. You can join in this prayer online at faustyna.pl, where it will be broadcast live.
