Cuiabá will see normal commerce operations during the Carnival period from Friday, February 13 to Tuesday, February 17, adhering to guidelines from local business leaders. The Chamber of Shopkeepers of Cuiabá stated that Carnival is not a national holiday and that there is no collective agreement designating it as such. Therefore, while some traditional stores may close on Tuesday and reopen on Ash Wednesday, it's ultimately up to each individual business owner to decide, without the requirement to provide double pay to employees. The city government has declared an optional holiday from February 16 to 18, during which there will be no operations in municipal administration offices. This decision reflects local customs and the broader legal framework surrounding holidays in Brazil. It illustrates how cities navigate traditions while accommodating operational needs and legal stipulations. Understanding these timings is essential for both residents and visitors in Cuiabá during this festive period, as it impacts commerce, public services, and social gatherings. This information helps plan for participation in Carnival activities while also managing day-to-day obligations amid the holiday policies.
