Father's Day (Dia dos Pais) in Brazil is celebrated on the second Sunday in August. The holiday was established in the mid-1950s by publicist Sylvio Bhering, who chose this date to honor Saint Joachim, the patron of fathers and grandfathers. Although many countries observe Father's Day on the third Sunday in June, Brazil opted for its own date, originally linked to the feast day of Saint Joachim, which was first added to the Roman Catholic liturgical calendar in 1584. While Father's Day is not an official holiday in Brazil, it is widely celebrated across the country, with families typically engaging in activities such as giving gifts to fathers. The celebration emphasizes family togetherness and appreciation for paternal figures.
