Europe Day is a day celebrating "peace and unity in Europe" celebrated on 5 May by the Council of Europe and on 9 May by the European Union.

The first recognition of Europe Day was by the Council of Europe, introduced in 1964. The European Union later started to celebrate its own European Day in commemoration of the 1950 Schuman Declaration which first proposed the European Coal and Steel Community, leading it to be referred to by some as "Schuman Day" or "Day of the united Europe". Both days are celebrated by displaying the Flag of Europe.

The Council of Europe (CoE; French: Conseil de l'Europe, CdE) is an international organisation founded in the wake of World War II to uphold human rights, democracy, and the rule of law in Europe. Founded in 1949, it has 46 member states, with a population of approximately 675 million, and operates with an annual budget of approximately 500 million euros.The organisation is distinct from the European Union (EU), although it is sometimes confused with it, partly because the EU has adopted the original European flag, created for the Council of Europe in 1955, as well as the European anthem. The Council of Europe is an official United Nations Observer.Being an international organization, the Council of Europe cannot make laws, but it does have the ability to push for the enforcement of select international agreements reached by member states on various topics. The best known body of the Council of Europe is the European Court of Human Rights, which functions on the basis of the European Convention on Human Rights.

The council's two statutory bodies are the Committee of Ministers, comprising the foreign ministers of each member state, and the Parliamentary Assembly, composed of members of the national parliaments of each member state. The Commissioner for Human Rights is an institution within the Council of Europe, mandated to promote awareness of and respect for human rights in the member states. The Secretary General presides over the secretariat of the organisation. Other major CoE bodies include the European Directorate for the Quality of Medicines and the European Audiovisual Observatory.

The headquarters of the Council of Europe, as well as its Court of Human Rights, are situated in Strasbourg, France. English and French are its two official languages. The Committee of Ministers, the Parliamentary Assembly, and the Congress of the Council of Europe also use German and Italian for some of their work.
