Marian Feasts are special celebrations in the Christian calendar that honor the Virgin Mary, the mother of Jesus. These feasts highlight her role in the faith and commemorate significant events in her life, such as the Annunciation and the Assumption. Different Christian denominations, including the Catholic Church and some Orthodox Churches, observe these feasts with various traditions and rituals. Each Marian Feast has its own date and significance, often marked by special prayers, masses, and processions. For example, the Feast of the Immaculate Conception celebrates Mary's conception without original sin, while the Feast of Our Lady of Guadalupe honors her appearance to Juan Diego in Mexico. These observances foster devotion and reflection among the faithful.
