October 16 - the feast of the Purity of the Blessed Virgin Mary.
Calvin did teach the perpetual virginity of Mary.
The concept of Mary's perpetual virginity is not explicitly stated in the Bible. While the Bible does affirm Mary's virginity at the time of Jesus' birth (Matthew 1:25), it does not provide direct support for her remaining a virgin throughout her life. The belief in Mary's perpetual virginity developed within the early Christian tradition and is supported by some indirect biblical interpretations and theological reasoning.
The four dogmas of the Blessed Virgin Mary are the Immaculate Conception, the Perpetual Virginity, the Divine Motherhood, and the Assumption. The Immaculate Conception refers to Mary's conception free from original sin. The Perpetual Virginity affirms that Mary remained a virgin before, during, and after the birth of Jesus. The Divine Motherhood declares that Mary is the mother of Jesus, who is both fully human and fully divine. The Assumption teaches that Mary was assumed into Heaven, body and soul, at the end of her earthly life.

The Catholic Church's teaching on mariology emphasizes the unique role of Mary as the Mother of Jesus and her special place in the life of the Church. This includes her title as the Mother of God (Theotokos), her perpetual virginity, and her assumption into heaven. Catholics honor and venerate Mary as a model of faith and obedience.
