Why is it celebrated on June 12th in Brazil, and on February 14th in many other countries?

1. Origin of Valentine's Day in the world: The legend of Saint Valentine
The oldest love-related celebration in February has roots in the Roman Empire. Around the third century, during the reign of Emperor Claudius II, marriage was prohibited for young soldiers—it was believed that single men were more productive on the battlefield.
Valentine, a Christian bishop, defied the order and performed secret marriages , helping couples in love to be together. For this, he was arrested and sentenced to death. It is believed that he was executed on February 14, 269 AD , a date later chosen to honor his martyrdom.
Over time, Saint Valentine was canonized and became a symbol of romantic love. The holiday spread throughout Europe in the Middle Ages and, centuries later, was embraced by countries such as the United States, Canada, the United Kingdom, and Japan.
2. Valentine's Day: How the World Celebrates Love
Valentine's Day , celebrated on February 14th, is more than a religious tribute: it's a cultural phenomenon. See how it's celebrated around the world:
🇺🇸 United States:
The holiday generates billions of dollars every year. Chocolates, flowers, and cards are the most popular gifts, and schools promote themed activities for children to participate in.
🇯🇵 Japan:
Interestingly, it is women who gift men with chocolates — a tradition that began as a marketing strategy in the 1950s. A month later, on White Day (March 14) , men reciprocate.
🇬🇧 United Kingdom:
The tradition of sending anonymous cards, known as "valentines," continues to this day. Poetic phrases and small gifts are also common.
🇫🇷 France:
Considered the most romantic country in the world, France transforms Valentine's Day into a true spectacle, with dinners, tours and even marriage proposals in iconic locations.
3. Why is Valentine's Day in Brazil on June 12th?
While the world celebrates in February, Brazil celebrates love on June 12. The explanation is less romantic, but very interesting.
In the 1940s, advertising executive João Doria (father of former governor João Doria Jr.) was hired to boost retail sales in June—a month considered slow for retail. Inspired by Valentine's Day, he created a campaign with the slogan:
“It’s not just with kisses that you prove love.”
The choice of June 12th was not random: it is the eve of Saint Anthony's Day (June 13th) , known as the "matchmaker saint." Thus, the date was strategically designed to unite love, religious tradition and commercial appeal.
The campaign was a success — so much so that Valentine's Day became a tradition in Brazil.
4. Commercial evolution of the date: from romanticism to marketing
