Today is the feast of St Augustine in the Ordinary and Extraordinary Forms, as well as the Benedictine 1962 calendar.
From the martyrology:
"At Hippo Regius, in Africa, the birthday of St. Augustine, bishop and famous Doctor of the Church. Converted and baptized by the blessed bishop Ambrose, he defended the Catholic faith with the greatest zeal against the Manicheans and other heretics, and after having sustained many other labors for the Church of God, he went to his reward in heaven. His relics, owing to the invasion of barbarians, were first brought from his own city into Sardinia, and afterwards taken by Luitprand, king of the Lombards, to Pavia, where they were deposited with due honors.
