For the Church to dedicate a month to the praying of the Rosary obviously means that there is something of spiritual importance that it wants to emphasise.
The feast of Our Lady of the Rosary was instituted on the 7th Oct 1571 to give thanks to God for granting the outnumbered and weaker Christian fleet a miraculous victory over the Ottoman navy at the Battle of Lepanto through the powerful intercession of Our Lady.
But even before that, the prayer of the Rosary had been a favourite prayer for the faithful, especially for the lowly and humble, because of its simplicity.
So when Pope Pius V rallied the Church to have recourse to Our Lady's intercession through the Rosary for the Christian fleet at the Battle of Lepanto, the Rosary became a popular devotional prayer.
Popes and Saints have spoken fondly and profoundly of the prayer of the Rosary as well as their devotion to Our Lady.
So it can be said that the Rosary is a tried, tested and proven prayer, and it is a prayer for all.
And since the prayer of the Rosary has stood the test of time and of every age, then all the more we should have confidence in that prayer in our time and age.
Our Lady calls out to us to pray with her the Rosary.
We only need to be humble and childlike to pray the simple prayers of the Rosary.
And God listens to the prayers of the humble and simple and He will let them see wonders and marvels, just as He had shown the Church on the 7th October 1571.
