What Spanish phrase means “party of fifteen years” and describes a quinceañera?

“Fiesta de quince años” means “party of fifteen years” and describes a quinceañera.

The phrase is a direct Spanish description of the celebration: fiesta means party, de means of, quince means fifteen, and años means years. It highlights the birthday milestone rather than a specific venue, dress, dance, or religious practice.

Quinceañera is the more familiar short name in many English-language contexts. Regional usage varies, and families may use quince, fiesta de quince, or other local expressions. These names generally refer to closely related celebrations rather than one rigid format.

The phrase also helps explain why the event is sometimes described as a “sweet fifteen,” by analogy with the English expression “sweet sixteen.” The cultural meaning, however, is distinct from an ordinary birthday party.
