What is the Spanish name for a quinceañera’s traditional fifteenth-birthday celebration?

The Spanish name for a quinceañera’s traditional fifteenth-birthday celebration is fiesta de quince años.

The phrase literally means “party of fifteen years” and refers to the celebration itself, while quinceañera can refer to the girl being honored, the event, or both depending on usage. In many Spanish-speaking communities, the event is also called quince años or simply a quince.

The celebration marks a transition associated with turning fifteen. It is often described as a coming-of-age tradition, but it is not legally equivalent to reaching adulthood. The legal age of adulthood varies by country and is separate from the customary age of the fiesta.

Regional names and practices differ across Latin America, Spain, the United States, and diaspora communities. A family may combine Catholic observances, formal court traditions, local foods, and contemporary music while still identifying the occasion as a fiesta de quince años.
