Overview
- Argentina’s last long weekend of 2025 runs Dec. 6–8 because the Dec. 8 Inmaculada Concepción is an inamovible Monday, while Christmas on Thursday, Dec. 25 will not extend the weekend.
- In Peru, consecutive national holidays on Dec. 8–9 create a four-day break when paired with the preceding weekend.
- Peru has designated Friday, Dec. 26, 2025 as a compensable non-working day for public employees, and private-sector adoption depends on employer–worker agreement.
- Two Buenos Aires localities, J. A. Pradere and Florentino Ameghino, declared Friday, Dec. 5 a local non-working day for anniversary observances that does not apply nationwide.
- For 2026 in Argentina, Holy Thursday falls on April 2 and coincides with the inamovible Malvinas Day, pointing to a four-day Holy Week nationwide even though the official calendar has not yet been released.
