As requested by the Blessed Virgin Mary in Montichiari, an hour of Grace on December 8 of each year (coincides with the Immaculate Conception).

On the first appearance the Blessed Mother told Sister Pierina that she wanted to be known as the ‘Mystical Rose,’ and that an hour of grace should be kept at noon, December 8th, in all the Catholic Churches of the world. The Blessed Mother wanted this to be known through all of Italy, and the entire world.
