Here's an interesting thought:
CARRY YOUR ROSARY EVERY DAY
When you carry a Rosary, Satan has a headache.
When you use it, he collapses.
When he sees you praying it, he faints.
Let us pray the rosary every time, so that he'll keep fainting.
Imagine what might happen if every Catholic in the world would pray a
Rosary on the same day! We have an example in October of 1573, when
Europe was saved from the invasion of the mighty Turkish fleet, by the
praying of the Rosary by all Christians!
Let's unite in praying one of the most powerful prayers in existence,
for these intentions, on one of the holiest seasons in our Church year.
God bless us all!
Wikipedia has this to say about October 1573:
The Battle of Lepanto took place on 7 October 1571 when a fleet of the Holy League, a coalition of Catholic maritime states, decisively defeated the main fleet of the Ottoman Empire.
The five-hour battle was fought at the northern edge of the Gulf of Patras, off western Greece, where the Ottoman forces sailing westwards from their naval station in Lepanto (Turkish: İnebahtı; Greek: Ναύπακτος, Naupaktos or Έπαχτος, Épahtos) met the Holy League forces, which had come from Messina. The Victory of the Holy League prevented the Mediterranean Sea from becoming an uncontested highway for Muslim forces, protected Italy from a major Ottoman invasion, and prevented the Ottomans from advancing further into the southern flank of Europe. Lepanto was the last major naval battle fought almost entirely between oar-powered galleys, and has been assigned great symbolic importance since then.
Since I am unable to find anything else on the internet about the event, other than the exact same message, I can't vouch for the praying of the rosary on that day... But the idea is still interesting.
