What Spanish term commonly names the quinceañera celebration itself as a “party of fifteen years”?

The Spanish term commonly naming the celebration as a “party of fifteen years” is fiesta de quince años.

The phrase literally combines fiesta, meaning party or festival, with de quince años, meaning of fifteen years. It is one of several expressions used for the tradition. Quinceañera can refer to the honoree and also to the event, while quince años is another widespread short form.

Usage varies across Spanish-speaking countries and families. Some communities use quinceañera most often; others say quince años or fiesta de quince años. English speakers may also call the event a quince, especially in the United States.

These names describe the same broad milestone but do not guarantee identical customs. Religious services, courts, special dances, dresses, gifts, and candle rituals differ by region and household. The phrase should therefore be understood as a name for a cultural celebration, not as a fixed program that every family must follow.
