Our Lady Of The Holy Rosary - 7 October

Quoted from Wikipedia [1]:

Our Lady of the Rosary, also known as Our Lady of the Holy Rosary, is a title of the Blessed Virgin Mary.

Quoted from Catholic News Agency [2]:

On October 7, the Roman Catholic Church celebrates the yearly feast of Our Lady of the Rosary. Known for several centuries by the alternate title of “Our Lady of Victory,” the feast day takes place in honor of a 16th century naval victory which secured Europe against Turkish invasion. Pope St. Pius V attributed the victory to the intercession of the Blessed Virgin Mary, who was invoked on the day of the battle through a campaign to pray the Rosary throughout Europe.  The feast always occurs one week after the similar Byzantine celebration of the Protection of the Mother of God, which most Eastern Orthodox Christians and Eastern Catholics celebrate on October 1 in memory of a 10th-century military victory which protected Constantinople against invasion after a reported Marian apparition.
