Egyptian Revolution Day takes place on July 23, 2017. Revolution Day refers to the public holiday in Egypt, the anniversary of the Egyptian Revolution of 1952. It is the biggest secular public holiday in Egypt. Annual celebrations marking the Revolution begin on the preceding evening, as the evening of 22 July 1952 was when the Free Officers Movement led by Muhammad Naguib and Gamal Abdel Nasser commenced the military coup d'état that launched the Revolution, and ultimately led to the abdication of King Farouk (the penultimate King of Egypt and Sudan). The public holiday itself is characterised by large and elaborate celebrations, including televised concerts with heavily nationalistic themes, and military parades.
