This idea to mess with school holidays keeps coming up. I don’t see the value in moving two weeks off from summer to typically gloomy and colder autumn and winter months. It’d also put overseas summer breaks well beyond more people because prices would skyrocket. https://www.theguardian.com/education/2024/feb/26/school-summer-holidays-half-term-england-calendar-nuffield-foundation-report
