Overview
- In Argentina, the next national holiday is Monday, May 25 for the May Revolution, which creates a three-day break from Saturday to Monday.
- Official schedules list more three-day breaks in 2026, including June 13–15, July 9–12, August 15–17, October 10–12, November 20–22, and December 25–27.
- Several observances shift to Mondays to build those breaks, including Martín Miguel de Güemes to Monday, June 15 and Soberanía Nacional to Monday, November 23.
- In Peru, the next non-working day after May 1 is June 7 for the Battle of Arica and Flag Day, and the 2026 calendar includes 16 national holidays under Decree 713.
- Fixed-date holidays that land on a weekend do not add a weekday off in Argentina, as with Flag Day on Saturday, June 20, which affects trip and leave planning.
