Overview

• The official DOF calendar runs from Sept. 1, 2025 to July 15, 2026 with 185 instructional days for basic education and 190 for teacher‑training schools, including scheduled CTE sessions and vacation periods.
• Authorities reiterate that Sept. 1 is not a statutory holiday under the Federal Labor Law and the presidential report does not alter the return date, with states only empowered to adjust calendars in extraordinary risk situations.
• Transport union FAT has called a Sept. 1 megablockade in the Mexico City metro area starting early morning, raising mobility concerns for drop‑off hours, yet education officials have not issued any delay.
• September breaks include the Independence Day holiday on Tuesday, Sept. 16 and the first CTE Friday on Sept. 26 that creates a long weekend; Sept. 15 is not an official day off.
• Separately, Spain’s regions set their own timetables, with Galicia starting classes on Sept. 8 and Extremadura on Sept. 11 for most stages as published in their official bulletins.
