When is Father's Day in 2025 and why is it celebrated on that date?
Argentina adopted an international tradition while Mendoza keeps its historical tribute to San Martín
Father's Day in Argentina has gradually become a celebration that combines local roots with a strong international influence. Its origin dates back to 1958, when it was proposed to commemorate the birth of Mercedes Tomasa de San Martín y Escalada, the only daughter of General José de San Martín.
That first celebration took place on August 24, a date chosen to pay tribute to the Argentine national hero, considered the "Father of the Nation". The initiative aimed to highlight his paternal and human role, beyond his military and political legacy.
The influence of the United States
During the 1960s, Argentina adopted the third Sunday of June as the official date for Father's Day, aligning with the American tradition. The decision was based on a moving story: in 1909, Sonora Smart Dodd proposed celebrating fathers in honor of her own father, William Smart, a war veteran who raised six children alone after being widowed.
Dodd's proposal quickly spread throughout North America and later to various countries around the world, including Argentina.
When Father's Day is celebrated this year
Thus, thanks to Dodd's initiative, the third Sunday of June became the most popular date, so in 2025 it will be Sunday, June 15.

Mendoza keeps its own tradition alive
Despite the national change, Mendoza decided to preserve the original spirit of the celebration. In 1986, the province enacted Law 5,131, which established August 24 as the official Father's Day within its territory. The regulation was promoted by legislators Duranti, Llorente, Américo, and Zgaib, and has remained in force ever since.

Over the years, this local version has gained strength. Although many families in Mendoza also celebrate in June, the August tribute remains present and is becoming increasingly culturally significant.
Father's Day in Argentina reflects a blend of identities: a national one, deeply connected to the figure of San Martín, and another adopted, but globally shared. Whether on June 15 or August 24, the essential remains: honoring those who guide, care for, and build through love.
