On what birthday is a traditional quinceañera held?

A traditional quinceañera is held on a girl’s 15th birthday.

The Spanish word quinceañera refers both to the celebrant and, commonly, to the celebration itself. The age is symbolically important because the event traditionally marks a girl’s transition from childhood toward young womanhood.

A quinceañera often combines a formal religious service, a large family celebration, music, dancing, and ceremonial presentations. Customs vary considerably among countries, families, and communities, so there is no single required format.

The tradition is especially associated with Latin America, Spain-influenced communities, and Latino communities in the United States. It is sometimes compared with a sweet sixteen party, but the quinceañera is specifically connected with the number 15 and has a distinct cultural and historical background.
