What is the traditional quinceañera ceremony called when it takes place during a Catholic church service?

A Catholic church service held as part of a quinceañera is called a Misa de acción de gracias, or Thanksgiving Mass.

The service gives the celebration a religious dimension: the quinceañera gives thanks for her life and asks for guidance during the transition toward adulthood. In many communities, the Mass takes place before the reception, although families may adapt the format to local customs or choose a nonreligious ceremony.

The Spanish phrase is sometimes confused with the name of the entire celebration. Quinceañera refers to the celebrant and, by extension, the birthday tradition; Misa de acción de gracias specifically identifies the Catholic worship service. Its wording also distinguishes it from an ordinary birthday Mass.

The service may include readings, prayers, a blessing, and the presentation of symbolic objects. Practices vary by country, parish, and family, so not every quinceañera includes a church Mass.
