Those who follow the 1970 Ordo observed the Visitation some time ago. But for those of us who follow the traditional Ordo, July 2nd is always the Feast of the Visitation.
My guess is that the 1970 Ordo observes the Visitation when it would have begun, while the traditional Ordo observes it at the time it would have ended.
My soul doth magnify the Lord,
And my spirit rejoiceth in God my Savior.
For He hath regarded the low estate of His handmaiden,
For behold, henceforth all generations shall call me blessed.
For He who is mighty hath done great things for me, and holy is His Name.
And His mercy is on those who fear Him from generation to generation.
He hath shown strength with His arm:
He hath scattered the proud in the conceit of their hearts.
He hath pulled down the mighty from their thrones,
And hath exalted those of low degree.
He hath filled the hungry with good things;
And the rich He has sent, empty, away.
He hath helped His servant Israel, in remembrance of His mercy;
As He spoke to our fathers, to Abraham, and to His posterity, forever.
Consecration to the Precious Blood
O Jesus, fairest of the children of men, Thou whom I see crushed beneath the weight of my sins, covered with wounds, Thy hands and feet pierced with nails, Thy side opened with a lance, I adore Thee and recognize Thee as my Lord and my God and as my beloved Redeemer. Pierced with grief at sight of the Blood flowing from Thy wounds for the redemption of souls, I feel irresistibly urged to consecrate myself to the worship of this regenerating Blood and, by an exemplary life, to atone for all the profanations of this Divine Blood and for those which It still receives daily in the veins of Thy Sacred Body present mystically on the altar. By this consecration which I beg Thee to accept, O my Savior, I desire to spend my whole life in proving to Thee my gratitude and my love by paying frequent homage to Thy Precious Blood and by propagating this devotion as far as is in my power. I desire every pulsation of my heart to be a renewal of this consecration, a constantly repeated act of love for this redeeming Blood, a perpetual offering of Its merits in behalf of sinners and all the souls dear to me, and a hymn of unceasing praise in union with that of the Saints and all the blessed in Heaven: "To the Lamb who redeemed us in His Blood, be honor and glory and benediction forever."
O Mary, Mother of the Divine Redeemer, obtain for me the grace of adoring fervently throughout my life the Blood of thy Divine Son and of singing forever Its mercies in Heaven.

Deus, qui hodiérnam diem Apostolórum tuórum Petri et Pauli martyrio consecrásti : da Ecclésiæ tuæ, eórum in ómnibus sequi præcéptum; per quos religiónis sumpsit exordium.
Let us pray.
O God, who didst hallow this day by the martyrdom of thine holy Apostles Peter and Paul, grant unto thy Church, whose foundations thou wast pleased to lay by their hands, the grace always in all things to remain faithful to their teaching.
