Mid-September Holidays Vary by Jurisdiction: Mexico’s Sept. 16 Is Mandated as Local ‘Megapuentes’ and Regional Days Off Spread

A web of state, municipal and sector rules is producing uneven school, bank and commerce schedules across Mexico, Argentina and Spain through September.

Overview

  • Mexico’s labor law makes Tuesday, Sept. 16 a mandatory paid holiday, and those who work that day are owed triple pay, with fines of 5,675 to 565,700 pesos per worker for employers who fail to comply.
  • The 15th is not a federal holiday in Mexico, so banks open Monday and close Tuesday under ABM and CNBV calendars, with ATMs and digital services operating.
  • The national SEP calendar keeps classes on Monday, Sept. 15, but local authorities have authorized school ‘megapuentes’ in Baja California, Mexico City, Yucatán, Durango, Querétaro and Veracruz.
  • In Argentina’s Buenos Aires Province, Resolution 157/2025 declares Friday, Sept. 26 a holiday in Maipú and Carmen de Areco, Trenque Lauquen set Monday, Sept. 15 as a local nonworking day, and Laprida and Cacharí observe Tuesday, Sept. 16.
  • Sector and regional calendars add further variation, with Argentina’s retail holiday moved to Monday, Sept. 29 closing many shops nationwide for that workforce, and Spain’s Cantabria marking Monday, Sept. 15 as a regional festivo.
