The traditional 15th-birthday celebration for a girl is called a quinceañera. The word can refer both to the celebrant and to the festival held for her.
Its spelling uses the Spanish letter ñ, producing the “ny” sound in English approximations. The related masculine term quinceañero is used for a boy’s comparable celebration in some communities, but it is not the standard feminine name.
A quinceañera may include a church service, a formal entrance, a court of attendants, a father-daughter dance, and a reception. No single schedule is universal, because regional and family customs shape the event.
