Overview

• Argentina’s official 2025 calendar lists no nationwide feriados in September, with the next national date on Sunday, October 12, and the next long weekend set for November 21–24.
• End‑of‑August local holidays include August 29 in La Angelita (General Arenales), Saldungaray (Tornquist), Merlo and Hurlingham, and August 30 in Bragado, Castelli, Tornquist and Merlo.
• Early September brings localized breaks with September 1 declared in Hilario Ascasubi (Villarino) and September 8 in San Pedro for its patronal feast, affecting public offices and Banco Provincia branches in those jurisdictions.
• Sectoral and religious observances still shape September for limited groups, including Rosh Hashanah on September 23–24 for the Jewish community, Teacher’s Day on September 11 with primary school closures, and Commerce Employees’ Day commonly observed around September 26.
• In regional contrast, Mexico recognizes September 16 as a statutory national holiday with triple pay if worked, while September 13 and 15 are not official rest days.
