What is the literal Spanish translation of “quince años”?

The literal Spanish translation of “quince años” is “fifteen years.”

Quince means fifteen, while años means years. In cultural usage, quince años commonly refers to the celebration of a girl’s fifteenth birthday, even though the literal phrase simply states the number of years. Fiesta de quince años makes the event meaning more explicit by adding “party.”

English speakers often encounter quince años and quinceañera as near-synonyms, but they are not identical in grammar. Quince años is a noun phrase naming the fifteen-year milestone or celebration, while quinceañera can identify the girl being honored and, in English, the event itself.

Neither phrase means “fifteen candles.” Candles may appear in some celebrations, but that is a separate custom and is not contained in the translation. Traditions vary across Latin America and Latino communities, so the language is more consistent than the exact program of the party.
