Traditionally, a quinceañera celebrates a girl’s 15th birthday.
The Spanish word quinceañera can refer both to the celebrant and to the birthday celebration. The event traditionally marks a transition from childhood toward young womanhood, although modern families may interpret that transition in different ways.
A quinceañera often combines a religious service, a formal reception, music, dancing, and symbolic presentations. Customs vary considerably by country, family, denomination, and community, so the exact program is not universal.
The celebration is especially associated with Latin America, Spain-influenced Caribbean communities, and Latino communities in the United States. It is not the same as a legal declaration of adulthood: the symbolic age is 15, while legal adulthood depends on the laws of the country involved.
