IB (International Baccalaureate) school calendars
54 schools following this curriculum, across 7 cities.
How the IB (International Baccalaureate) year is shaped
IB schools typically start in mid-to-late August, break for a week in October, two at Christmas, and sit the DP examinations across most of May.
35 of these 54 schools publish staff training days (INSET / PD) — days the school is shut to students but most workplaces are not. Those are the dates worth checking first if you need childcare.
Fall Conferences (no school)
Oct 30 – Oct 30, 2026
Counted as the earliest school-holiday start among the 54 IB (International Baccalaureate) schools below. They publish their own calendars and do not all break in the same week, so the school that breaks first is not the family breaking — each school's own dates are listed below.

Source and data
This page restates the calendars of 54 IB (International Baccalaureate) schools, collected from each school or its authority and published as one dataset at /data/schools-compact.json. There is no single IB (International Baccalaureate) calendar, so there is no single source here: every school above links to its own.
Data collected for this dataset. It is the date the whole dataset was collected, not a per-school verification date: a school may have published its dates earlier, and any of these calendars can change after it.
A school's calendar can change mid-year. Confirm against the school's own publication before booking travel.
Spotted a wrong date, or a school that has republished its calendar? Report a date error or source change — name the school in the details, or use the per-school report link in the list above so that the school's own source URL travels with the report.
