Overview
- The national calendar confirmed that the San Martín commemoration falls on Monday 17 August 2026, creating a three‑day long weekend from Saturday 15 to Monday 17.
- The holiday is legally trasladable but was not moved this year because it already falls on a Monday, a detail the government kept when finalizing the official calendar.
- National public agencies, banks and schools will be closed on the holiday and workers who must work that day are entitled to special higher pay under Argentina’s labor rules.
- Several Buenos Aires municipalities have separate local non‑laborable days at the end of July—Guaminí and General Villegas on 28 July and Saladillo, Junín and Los Indios on 31 July—that affect only local public activity.
- After the August break the official calendar still lists additional long weekends in October, November and December while September has no national holiday except for Tucumán’s provincial observance on 24 September.
