The number central to the age traditionally celebrated by a quinceañera is fifteen.
A quinceañera marks a girl’s fifteenth birthday. The term comes from the Spanish quince, meaning fifteen, and the feminine ending associated with a female celebrant. The corresponding celebration is also called a fiesta de quince años or simply a quince.
The event is often described as a coming-of-age celebration, although its meaning differs among families and countries. In many traditions, it combines a birthday party with a formal presentation, religious service, symbolic gifts, music, and dancing.
Fifteen should not be confused with the legal age of adulthood. Laws governing adulthood, marriage, voting, and other rights vary by country and are unrelated to the celebration’s traditional number. Likewise, families may hold the party later or earlier because of finances, scheduling, or personal preference.
