Argentina observes national holiday for José de San Martín

Argentina observes a national holiday on Monday, August 17, 2026, to commemorate the 176th anniversary of the passing of General José de San Martín. The long weekend includes various civic-military parades and commemorative acts across several cities, including Córdoba, San Isidro, and Formosa.

Public services will see adjustments during the holiday. In Buenos Aires, hospitals will maintain 24-hour emergency services, while external clinics and vaccination centers will close. Public transport, including subways, will operate on reduced schedules. Banks will be closed for 72 hours due to the holiday falling on a Monday, though digital banking and ATMs remain available.

Politically, the holiday coincides with President Javier Milei's expected return to public view after a period of absence from the daily management of government, which was largely handled by his sister, Karina Milei.
