Quinceañero is the Spanish word commonly used for a boy celebrating a corresponding fifteenth-birthday ceremony.
Quinceañera is the feminine form traditionally associated with a girl and her celebration at age fifteen. Quinceañero is the masculine counterpart. English-language usage often retains quinceañera as the name of the broader tradition, even when families adapt the event for a boy.
A quinceañero celebration can include formal clothing, family presentations, music, dancing, religious elements, and symbolic customs. The exact structure depends on the family and community, and there is no single worldwide format required for boys or girls.
The word should not be confused with quincenal, which means “biweekly” or “fortnightly” in Spanish, or with quinceavo, which relates to a fifteenth part. The accent and ñ in quinceañero are part of the standard spelling.
