Wait, is Finland not Scandinavia?
Finland is, in fact, not an Scandinavian country. Denmark, Sweden and Norway are Scandinavian countries, while the three Scandinavian countries and Finland and Iceland make up the Nordic countries, and the Nordics also include the autonomous areas of Greenland, Faroe Islands and Åland.
In the English language, the two terms are often used synonymously, but in the Nordics, the two terms wouldn't be used interchangeably. This is because of geographical and cultural reasons: Geographically, Scandinavia refers to the Scandinavian peninsula, which Finland is not a part of (aside of the northernmost parts of the country), and culturally Swedish, Norwegian and Danish are Scandinavian languages, while Finnish is a Finno-Ugric language. Although Denmark also isn't located on the Scandinavian peninsula either, Danish is a Scandinavian language. There's also historical and political reasons for the distinction.
But yes, very much understandable if you didn't know this since at least English treats the two terms as synonyms, I'm not sure if other languages treat them as the same or not.
