This article explores 'peace days' in English schools as a form of peace education. From a historical overview of academic discussions on peace education in the US and Great Britain since the First World War, we identify three key factors important for peace education: the "political" context, the "place" in which peace days occur and "pedagogical" imperatives of providing a certain narrative of the sources of violence in politics. Although contemporary militarism and neoliberalism reduce the terrains for peace studies in English schools, peace days allow teachers to carve out spaces for peace education. Peace days in Benfield School, Newcastle and Comberton Village College, Cambridgeshire, are considered as case studies. We conclude with reflections on the opportunities and limitations of this approach to peace education, and on how peace educators and activists could enlarge its reach.
