Queenship of Mary - August 23, 2012

On the 11th of October 1954, Pope Pius XII established the Feast of the Queenship of Mary to be celebrated throughout the world, and commanded that on that day each year, the world should renew its consecration to her:

“We have decided to institute the liturgical feast of the Blessed Virgin Mary, Queen. This will afford a climax, as it were, to the manifold demonstrations of Our devotion to Mary, which the Christian people have supported with such enthusiasm... The purpose of the Feast is that all may recognize more clearly and venerate more devoutly the merciful and motherly sovereignty of her who bore God in her womb… Let all Christians, therefore, glory in being subjects of the Virgin Mother of God, who, while wielding royal power, is on fire with a mother's love... by Our Apostolic authority We decree and establish the feast of Mary's Queenship, which is to be celebrated every year in the whole world on the 31st of May” (Ad Coeli Reginam).

On the day of her Assumption, Mary our Mother was solemnly crowned by Christ and received by the whole court of Heaven as Queen. What Christ has done in Heaven and the Church has done on our behalf, we should do individually — that is, we should now recognize Mary's Queenship, enthrone her in our homes, consecrate ourselves to her and, by this means, establish in our lives the reign of Mary Immaculate Queen of the Universe

This year the feast day is on August 23, 2012.  The Novena prayer can be prayed anytime throughout the year.  Traditionally it is prayed nine days before the feast day:   http://www.angelqueen.org/forum/viewtopic.php?t=37440
