What is the Spanish name for the thanksgiving Mass sometimes held as part of a quinceañera?

The thanksgiving Mass associated with some quinceañeras is called a Misa de Acción de Gracias.

The phrase literally means “Mass of thanksgiving.” In families that include a Catholic religious service, it provides an opportunity to give thanks for the celebrant’s life and to ask for blessings as she enters a new stage. The Mass may take place before the reception, although the order and details vary.

Not every quinceañera includes a Mass. Some families hold a secular party, while others choose a prayer service, another religious ceremony, or no formal service. Regional customs and the family’s religious affiliation shape the program.

This term should not be confused with the general phrase quinceañera Mass in English. Acción de Gracias identifies the thanksgiving purpose of the service; it does not mean the U.S. holiday Thanksgiving. The celebration’s reception and religious service are related but separate parts of the event.
