The Mexican Secretariat of Public Education (SEP) released the 2026-2027 school calendar for preschool, primary, and secondary education, spanning August 31, 2026, to July 9, 2027. The schedule includes 185 school days and various breaks for holidays and teacher planning sessions. As the academic year approached, the SEP issued guidance to help families manage the costs of school supplies. Despite these efforts, parents reported financial strain due to inflation. Additionally, Alejandro Águila Argüelles of the National Association of Parents (ANPAF) criticized the educational system, stating the calendar fails to address educational gaps and that political matters are distracting teachers. Following the initial calendar release, local authorities in Mexico City confirmed a specific holiday period for September 15 and 16, 2026. While September 16 is a national holiday for Mexican Independence, the additional closure on September 15 was implemented to allow for family participation in celebrations. ## Timeline ### 2026-09-14: Mexico City schools to close September 15-16 for holidays The SEP confirmed that basic education schools in Mexico City will be closed on September 15 and 16, 2026, for the Independence Day festivities. 3 sources. https://clstr.news/cluster/mexico-city-schools-to-close-september-15-16-for-holidays ### 2026-08-22: Mexico's SEP confirms 2026-2027 school calendar and key dates Mexico's SEP has set the 2026-2027 school calendar, starting August 31, 2026.
