🇧🇷Does Brazil have Diwali Dates and Holidays?

Not observed here

There is no Diwali in Brazil. The nationwide holidays are set by Law 662 of 1949, which fixes seven civil dates, plus Law 6.802 of 1980, which adds 12 October for Our Lady of Aparecida. Religious days are handed by Law 9.093 of 1993 to the municipality: each may declare days of observance by municipal law according to local tradition, no more than four, and Good Friday already takes one of those slots. So in Brazil the question of whether a religious festival is a day off is answered not federally but by the town you live in — and there are only four slots to give.
