how Brazil's national holidays are calculated
Not every Brazilian holiday falls on the same date every year: nine are fixed by federal law, and three come out of a calculation over the date of Easter. This page explains that calculation, the difference between a national holiday and a discretionary day off, and what changes when a holiday is only municipal, before you check the calendar in the tool.
Before Lei 14.759/2023 this date was a holiday only in some states and cities; from 2024 on it joined the national list alongside the other eight fixed holidays.
The calculation adds 60 calendar days to that year's Easter date; because Easter moves, Corpus Christi never falls on the same date two years in a row.
Public agencies usually suspend business by decree year after year, but no federal law forces the closure; shops and private companies decide for themselves whether to open.
No. This page is focused on nation-wide holidays. State holidays, city holidays and local optional closures can vary according to each place's law and should be checked separately.
Through the Gregorian computus, an algorithm (the most used version is Meeus/Butcher) that combines the 19-year lunar cycle with the solar calendar to find the first Sunday after the first full moon of the northern hemisphere's spring; that date is what sets Carnival, Good Friday and Corpus Christi every year.
No. Carnival is a nationwide discretionary day off, decreed year by year for federal civil servants; unlike the nine fixed holidays and Good Friday, there is no permanent federal law forcing shops to close on that day.
Since 2024, under Lei 14.759/2023; before that, November 20 was a holiday only in states and municipalities that had their own legislation on the topic, not across the whole country.
A national holiday applies across all of Brazil and comes from federal law; a municipal holiday applies only inside one city, created by local law, usually tied to the municipality's founding date or a patron saint, and it never appears on any national calendar.
Green: national holiday. Amber: nation-wide optional closure. State and city holidays are not in this list.
