Commemorates the day on which the Guadalupana (the Virgin of Guadalupe) appeared to San Juan Diego and her image appeared on his tilma (apron). The miraculous roses Juan Diego found and carried to the Bishop took the form of the image of Mary exactly as she had appeared to him at the hill of Tepeyac.
