Use the `finnish` tag for questions specific to the Finnish language.
The finnish tag is for questions specific to the Finnish language. As you might expect, such questions are relatively rare on a programming site. Nevertheless, there is one question that uses this tag, and efforts to remove it have been futile. Evidently, at least one user feels that this tag is actually necessary and valuable, presumably because "there are, depending on the context, different ways to represent a day or month in the Finnish language." So we may as well write it up.
