If the question is which date is the official National Poetry Day in Brazil, the answer today is October 31. The date was established by Federal Law No. 13,131 of June 3, 2015, in honor of Carlos Drummond de Andrade's birthday. The traditional March 14, associated with the birth of Castro Alves, still appears in cultural calendars and tributes, but it does not have the same federal legal status.
What Law 13,131/2015 establishes
The law is short and direct. Article 1 establishes National Poetry Day as an annual observance on October 31 and explains why: the date corresponds to the birth of Carlos Drummond de Andrade. The law was enacted on June 3, 2015, and published in Brazil's Official Gazette on June 5 of that year.
The legislative history also shows that the choice was deliberate. The proposal originated in the Senate as PLS 501/2009, introduced by then-senator Alvaro Dias, and moved to the Chamber of Deputies as PL 3694/2012. After congressional approval, the bill became Law 13,131/2015.
Why October 31 honors Drummond
Carlos Drummond de Andrade was born on October 31, 1902, in Itabira, Minas Gerais, according to Brazil's National Digital Library. The connection between the date and the poet is therefore not merely symbolic: the federal law itself states that the observance honors Drummond's birthday.
Drummond is a central figure in twentieth-century Brazilian poetry. His work moved through modernism, everyday life, memory, social experience and reflection on the individual, in books such as Alguma Poesia, Sentimento do Mundo and José. The law does not create a ranking among poets or claim that he is the only figure able to represent Brazilian poetry; it simply sets an official reference and names the writer selected for the tribute.
Where March 14 comes from
March 14 is linked to Antônio Frederico de Castro Alves, who was born on that date in 1847. The Brazilian Academy of Letters lists Castro Alves as patron of Chair No. 7 and highlights a poetic career marked, among other themes, by abolitionism.
The tradition of celebrating poetry on March 14 predates the 2015 law. A Chamber of Deputies legislative record for a bill introduced in 1977 includes documents stating that the Grêmio Brasileiro de Trovadores had launched the observance in 1968, specifically on Castro Alves's birthday. The 1977 bill itself proposed making March 14 National Poetry Day.
But a cultural tradition and a federal law are not the same thing. A 2017 report from the Chamber's Culture Committee summarized the history clearly: Brazil had already been observing National Poetry Day on March 14 in honor of Castro Alves, without that observance being backed by a federal legal text. This is the key to understanding why both dates still appear in searches, calendars and school activities.
Did October 31 replace March 14?
In federal legal terms, October 31 is the official reference established by law. Therefore, when a school, public agency, publication or calendar needs to identify the National Poetry Day set by Brazilian legislation, October 31 is the correct date.
At the same time, it would be inaccurate to say that March 14 has lost all meaning. It remains a historic date for honoring Castro Alves and poetry, built through decades of cultural use. What changed with Law 13,131/2015 was the existence of a national date expressly defined in federal law: October 31.
| Date | Honoree or reference | Status |
|---|---|---|
| October 31 | Carlos Drummond de Andrade, born October 31, 1902 | National Poetry Day established by Law 13,131/2015 |
| March 14 | Castro Alves, born March 14, 1847 | Traditional Brazilian poetry observance, without the same federal statutory basis |
| March 21 | Poetry as a worldwide cultural and linguistic form of expression | World Poetry Day adopted by UNESCO in 1999 |
Why both Brazilian dates still appear
The coexistence has a straightforward historical explanation. March 14 circulated for many years as National Poetry Day before the 2015 federal law existed. A cultural memory does not disappear automatically when legislation creates another official reference. That is why events, schools and institutions may still use March to remember Castro Alves and celebrate poetry.
October 31, however, should be used when the question specifically concerns the official date established by law. The clearest wording is: October 31 is Brazil's National Poetry Day established by federal law; March 14 is the traditional date associated with Castro Alves.
What about March 21?
There is a third date that often enters the same discussion. UNESCO celebrates World Poetry Day on March 21. The organization adopted the date in 1999 with goals that include promoting poetic expression, linguistic diversity, reading, writing and the teaching of poetry.
The three dates therefore refer to different frameworks: October 31 is the national date established by law in Brazil; March 14 preserves a Brazilian tradition associated with Castro Alves; and March 21 is UNESCO's worldwide observance.
How to cite the date without confusing readers
- When referring to the official Brazilian date, use October 31 and cite Law 13,131/2015.
- When explaining March 14, note that it marks Castro Alves's birthday and was traditionally treated as National Poetry Day before the 2015 law.
- For the international observance, use March 21 and identify it as UNESCO's World Poetry Day.
This distinction preserves both Brazilian literary references without setting them against each other. Drummond is the honoree of the official date defined by federal law; Castro Alves remains at the center of the March 14 tradition, which explains why that commemoration still appears in many calendars.
