According to Catholic tradition, Juan Diego reported seeing Mary at Tepeyac.
The Guadalupe tradition places the reported appearances in December 1531, shortly after the Spanish conquest of Mexico. Juan Diego, an Indigenous Christian, is said to have encountered Mary, who asked that a church be built at Tepeyac. The story includes the presentation of roses and the image associated with the Virgin of Guadalupe.
Because some quinceañera ceremonies incorporate Mexican Catholic symbols, knowledge of Juan Diego can help explain why Guadalupe imagery may appear at certain celebrations. This connection is cultural and religious rather than a mandatory quinceañera rule.
Juan Diego was canonized by Pope John Paul II in 2002. The historical interpretation of the apparition tradition has been debated, but the question asks specifically about the account preserved in Catholic tradition.
