Slovenia has three national symbols – the coat of arms, the flag and the anthem. The coat of arms, the flag and the anthem are determined by the Constitution. Their use is determined by the law, which among other things prescribes the flying of the flag on state holidays.

Slovenia joined the European Union on 1 May 2004. The use of the European Union’s flag and anthem in Slovenia is determined by the Decree on the use of the European Union's flag and anthem in the Republic of Slovenia (Uredba o uporabi zastave in himne Evropske unije v Republiki Sloveniji , Official Gazette of the Republic of Slovenia).
