A public-holiday calendar records the days Brazil has set aside as statutory time off. National holidays apply nationwide; where an official regional or provincial list is published, those dates are included separately and clearly labelled rather than folded into the national figures. This calendar is a reference, not a legal determination of anyone's leave entitlement. Dates move for two common reasons: many countries observe a fixed-date holiday on the nearest working day when it falls at a weekend, and some observances follow lunar or other non-Gregorian reckoning that shifts against the everyday calendar. Regional holidays are always shown as regional and never added to the national count. The licence terms and the government producer behind each list are credited on the sources page.
Reading the table
The table gives the date a holiday falls on, the observance date when a weekend shift or substitute day applies, and notes published with the source. A Regional · <region> badge marks a holiday that applies only in that region; it is never counted as nationwide. Some countries publish both the original date and the observed date, so both are shown instead of silently adjusting one. Employers, schools, and individual workplaces may follow different calendars or grant extra days, so treat this table as a guide rather than an entitlement. For a wider comparison of why observance moves between countries, see why holiday dates differ between countries. The official source is always the final authority.
Where these dates come from
Brazil's national public holidays are fixed by federal law, principally Lei nº 662/1949 and later amendments, and are republished from government material under Brazil's open-data terms. The national list covers the civil and religious dates observed across the country; state and municipal holidays vary widely and no single official open-licence regional calendar was identified, so the desk is national only. Carnival, Good Friday and Corpus Christi are moveable dates tied to Easter and are shown on their actual days. Brazil does not apply a general weekend substitute rule, so a fixed date is listed as it falls. Because the national list is set by statute, it changes only when Congress or the federal government amends it; the desk is refreshed from the official material rather than edited by hand. Some dates widely treated as holidays, such as Carnival, rest on custom or state law rather than the federal statute, and municipal holidays can add further dates in a given city. The national list is a fixed set, with the moveable dates computed from the date of Easter.
