In his encyclical Ad Caeli Reginam, Pope Pius XII proclaimed the memorial of the Queenship of Mary following the 8th day after the feast of the Assumption (https://www.vatican.va/content/pius-xii/en/encyclicals/documents/hf_p-xii_enc_11101954_ad-caeli-reginam.html).
Hail, holy Queen
Hail, holy Queen, Mother of mercy, our life, our sweetness and our hope. To thee do we cry, poor banished children of Eve. To thee do we send up our sighs, mourning and weeping in this valley of tears. Turn, then, most gracious advocate, thine eyes of mercy toward us, and after this, our exile, show unto us the blessed fruit of thy womb, Jesus. O clement, O loving, O sweet Virgin Mary.
V. Pray for us, O holy Mother of God.
R. That we may be made worthy of the promises of Christ.
