September 15th is not a national holiday in Brazil. The date is commemorative only at the municipal level, celebrating patron saints or city anniversaries, which means only some cities in the country will have the day off on that day.
Our Lady of Sorrows is one of the most celebrated patron saints on this date, mainly in municipalities in Ceará, such as Juazeiro do Norte, and also in cities in Minas Gerais.
In Limeira, in the state of São Paulo, the celebration is twofold, covering both the saint and the city's anniversary. Ponta Grossa, in Paraná, also marks the date with the celebration of its founding.
In Rio de Janeiro, the city of Magé celebrates its patron saint, Our Lady of Piety, on this September 15th.
