“Quince años” means “fifteen years” in Spanish.
The phrase directly identifies the age associated with the celebration. Quince means fifteen, while años means years. Together, the words are often used for the birthday milestone or for the fiesta de quince años itself.
English speakers may encounter several spellings and forms, including quinceañera, quince años, and fiesta de quince años. They are related but can emphasize different parts of the tradition: the celebrant, the age, or the party.
Pronunciation and local usage vary, but the numerical meaning does not. The expression should not be mistaken for a reference to fifteen guests, fifteen dances, or a fifteen-day festival.
