Before we started the Rosary last night, we checked the 1961 Missal. It says to use the Sorrowful Mysteries from Ash Wednesday to Easter.
St. Michael, the Archangel, defend us in battle
Be our protection against the wickedness
and snares of the devil;
May God rebuke him, we humbly pray,
and do thou, O Prince of the heavenly host,
by the power of God,
Cast into hell Satan and all the evil spirits
who prowl through the world seeking the ruin of souls.
Amen
