The Feast of the Presentation of the Theotokos commemorates the day Mary, the mother of Jesus, was presented at the Temple in Jerusalem as a child. According to tradition and apocryphal texts like the Protoevangelium of James, Mary's parents, Joachim and Anna, dedicated her to God in thanksgiving for her birth. The celebration on November 21st (Gregorian calendar) is a major feast day in Orthodox Christianity, symbolizing her lifelong consecration and the beginning of God's plan for salvation.
