The Feast of Our Lady of Guadalupe, celebrated on Dec. 12, is a significant religious and cultural observance in Mexico and the Roman Catholic community, honoring the Virgin Mary as she appeared in four visions before Indigenous Mexican convert St. Juan Diego in 1531.
According to Britannica, the religious tradition recounts how Mary revealed herself to Juan Diego on four occasions between Dec. 9 and 12, 1531, on Tepeyac Hill near present-day Mexico City.
