A quinceañera traditionally celebrates which birthday in a girl's life?

A quinceañera traditionally celebrates a girl’s 15th birthday.

The Spanish word quinceañera is related to quince, meaning fifteen. The celebration marks an important transition from childhood toward young adulthood in many Latin American and Latino families. It is usually held on or near the girl’s fifteenth birthday.

The customs are not identical everywhere. Some families emphasize a religious service, while others focus on a formal reception, music, dancing, and family traditions. The celebration may also be adapted by families living outside Latin America.

A quinceañera is sometimes compared with a sweet sixteen party, but the traditions are distinct. The age fifteen is central to the quinceañera tradition, whereas a sweet sixteen specifically marks a sixteenth birthday.
