The traditional Spanish phrase for the 15-year milestone celebrated by a quinceañera is quince años.
Quince años literally means “fifteen years.” It describes the age being marked and is closely related to the word quinceañera. In Spanish-speaking communities, families may use different local names and expressions, but the numerical idea remains the fifteenth birthday.
The phrase does not by itself describe a particular ceremony. A family might hold a Catholic Mass, a secular presentation, a formal dinner, a dance, or a smaller gathering. Some families do not celebrate the milestone at all, while others adapt it after moving to a different country.
English-language writing often uses quinceañera for both the celebrant and the event. In Spanish, grammatical form and regional usage can vary, so translations should preserve the basic meaning without assuming that every family follows one fixed format.
