Editorial policy and corrections

Plan a trip around a holiday that does not exist in your city and you are at work while everyone else is away. This page explains where every date comes from and what happens when something is wrong.

Order of sources

Federal laws as in force, read on the official federal portals: Laws 662/1949, 6,802/1980, 9,093/1995 and 14,759/2023;
State constitutions, laws and decrees on the state assemblies' and governments' portals; where the law itself could not be opened, an official text that applies it (a state decree, or a court or prosecution service ordinance), named as such;
Municipal laws of the state capitals, on the city's or council's portal;
The Ministry of Management's yearly ordinance for federal optional days off.

Calendar sites, newspapers and travel portals are not a source. A date that has been struck down by the Supreme Court, revoked, or that only appears on private lists is shown as "not a holiday" with the reason, not in the count.

Computed, not copied

No date on this site is typed by hand. An engine derives each holiday from its rule: fixed day, offset from Easter (Carnival, Good Friday, Corpus Christi), or a date set by decree. Automated tests compare Easter with a second, independent formula over a thousand years, check the national list, Acre's Friday rule and the long-weekend planner on every change.

Review cycle

A full review at least every 12 months, each December when the federal ordinance for the next year comes out, and after any change to a holiday law we are told about.

Handling errors

Check against the official text.
Fix the rule in the engine and add a test.
New date on every page.

Independence

No money from travel companies, hotels or governments. No affiliate links, no paid content, no lead forms.
