Overview
- The Jefatura de Gabinete’s official 2026 calendar names Monday 17 August 2026 as the national commemoration of the Paso a la Inmortalidad of General José de San Martín, producing a three-day long weekend from Saturday 15 to Monday 17.
- Sunday 16 August is the Día del Niño this year, so the weekend is likely to concentrate family outings and short trips across the country and raise demand in tourism and retail sectors.
- Two municipalities in Buenos Aires Province—Quilmes and the town of Bartolomé Bavio in Magdalena—will observe a separate local holiday on Friday 14 August for founding anniversaries, creating a longer break for residents there.
- Reporting differs on technical points: some outlets call the 17 August entry 'inamovible' while others label it 'trasladable,' and at least one source attributes the 2026 feriados calendar to a decree by President Javier Milei.
- Workers required to work the holiday are entitled to extra pay under Argentina’s labour rules, and the published calendar also lists remaining long weekends through October, November and December that will shape travel and municipal planning.
