The Catholic feast of Our Lady of Guadalupe is observed in December.
The feast day is December 12, commemorating the reported appearances of Mary to Juan Diego at Tepeyac in 1531, according to Catholic tradition. Our Lady of Guadalupe holds particular importance in Mexico and in many Mexican and Mexican American communities.
Some quinceañeras include prayers, images, or religious dedications connected with Guadalupe, especially when the family has Mexican Catholic ties. This is a possible cultural or religious element, not a required part of every quinceañera.
The feast should not be confused with the date of a particular quinceañera. Families can schedule the birthday celebration in any month. Similarly, not every quinceañera is Catholic, and many families adapt the event to their own religious beliefs or choose a secular ceremony.
