On the final day of the 2025-2026 cycle in Mexico, a parent in the capital refreshed a government portal, only to be met with a maintenance notice. The Secretaría de Educación Pública (SEP) had taken its report-card download system offline, overwhelmed by 1.2 million simultaneous requests from families of preschool, primary, and secondary students. The digital bottleneck, announced as “preventive maintenance,” was a small, revealing glitch in the vast machinery of a nation’s school calendar.

The system was restored at 10 a.m. on Thursday, 16 July, just as 23.3 million basic-education pupils and 1.2 million teachers began their summer break. On the same day, the SEP published the 2026-2027 calendar in the Diario Oficial de la Federación: 185 days of classes starting 31 August, punctuated by eight teacher council sessions, nine public holidays, and two vacation periods. The rhythm is familiar, yet beneath it, teachers in Mexico City told reporters that they still lack clarity on the promised replacement for the controversial teacher-evaluation system, Usicamm, and on the implementation of the Nueva Escuela Mexicana curriculum, now in its third year.

Half a world away, in Lagos, Nigeria, the state government released its own harmonised calendar for public and private schools, fixing resumption for 14 September 2026. The 182-day session, announced by Commissioner Jamiu Alli-Balogun, mandates staff professional development days in early September and compulsory Open Days, while granting schools running international curricula a window to apply for flexibility. The document meticulously lists public holidays, from Eid-el-Fitr to Workers’ Day, and insists on strict compliance, with a deadline of 21 August for international schools to request adjustments—a bureaucratic insistence on uniformity that mirrors Mexico’s centralised planning, even as local realities diverge.

In Iran, the education minister, Alireza Kazemi, used a visit to a school-opening ceremony in Ramsar to dismiss rumours about the coming year’s format. “Our planning is one hundred per cent based on in-person education,” he said, though he added that national conditions would be weighed. He spoke of 50 days of study leave for students, a week’s exam delay due to a leader’s funeral, and a race to finish before the Arbaeen pilgrimage. His remarks, carried by Iranian media, also promised server upgrades for the Shad online platform—a nod to the hybrid legacies of the pandemic era that linger across all three countries—and announced a 10-billion-toman allocation for a student research centre, plus at least ten artificial-turf pitches in western Mazandaran, weaving infrastructure pledges into a broader call to strengthen religious beliefs and revolutionary identity.

As the Mexican school year ended with a digital hiccup and a paper calendar, the parallel announcements from Lagos and Tehran sketched a shared global moment: the annual turning of the academic page, always a mix of meticulous planning and last-minute improvisation, of servers that crash and ministers who reassure, while millions of children simply step into the summer.
