There is no standard calendar for international schools although they are very similar to each other. School calendars and holiday schedules will differ by each international school. Check individual international schools’ websites for their latest academic calendars.
Chinese public school calendars usually consist of two semesters, starting in September and March, with a summer break in July and August.
