Comment: I support deletion because I've read quite a few reliable sources on the topics of astronomy and calendars, and have never heard of a rotational year. There are no reliable sources mentioned in the article mention "rotational year", so the article topic does not satisfy the otability guideline. A Google search does not produce any hits outside Wikipedia for this concept in the first few pages of search results
