The traditional celebration of a girl's fifteenth birthday is commonly called a quinceañera.
The term is used in two related ways: it can describe the young woman reaching the milestone, and it can describe the ceremony and party held for her. The Spanish expression fiesta de quince años, meaning “party of fifteen years,” is another widely used name for the event.
Quinceañera customs differ across regions and families. A celebration may include a church service, a reception, a formal gown, a court of attendants, a waltz, and symbolic gifts. These elements are customary rather than universal, so no single sequence applies to every quinceañera.
