What is the common English translation of the Spanish phrase fiesta de quince años?

The Spanish phrase fiesta de quince años translates as “fifteenth-birthday party.”

Fiesta means party or celebration, quince means fifteen, and años means years. Together, the phrase identifies a celebration held for a girl reaching fifteen. It is one of several Spanish expressions used for the tradition, alongside quinceañera, quince años, and fiesta de quince.

English-language communities often use quinceañera for both the celebrant and the event, while Spanish usage can distinguish the person from the fiesta. Regional vocabulary is not perfectly uniform, so speakers may prefer different names. The translation also helps separate the tradition from a sweet sixteen party, which is a different birthday custom associated especially with English-speaking North America.
