The celebration on January 1st has evolved over time:
- Ancient Roots: Devotion to Mary as Mother of God is ancient, affirmed strongly after the Council of Ephesus. Early celebrations focused on Mary were often linked to Christmas.
- Octave of Christmas: January 1st falls exactly one week after Christmas Day, marking the octave day. Historically, this day also commemorated the Circumcision of Jesus, reflecting his submission to Jewish law.
- Feast Evolution: For centuries, January 1st was primarily focused on the Circumcision. While Marian feasts existed, a universal feast specifically honoring Mary's Divine Maternity on Jan 1st was established more recently in the liturgical calendar.
- Liturgical Reform (1969): Following the Second Vatican Council, the Roman Calendar reform emphasized Mary's role as Mother of God on this day, aligning with ancient tradition and the Christmas season's focus on the Incarnation. The Circumcision aspect became secondary.
- World Day of Peace: In 1967, Pope Paul VI designated January 1st as the World Day of Peace, adding another layer of significance to the date, praying for peace under Mary's patronage.
