Wikipedia:Articles for deletion/Dates in Harry Potter
This is a tough one.  On the one hand, it ''is'' true that the page is in-universe and therefore doesn't comply with the Wikipedia:Manual of Style (writing about fiction)|fiction style guide, and that nothing on the page independent satisfies the |notability guideline.  On the other hand, failure to comply with a style guide is normally an issue for clean-up, not deletion, and there's a good argument that since Harry Potter as a whole is notable, this particular topic, if encyclopedic, would be appropriate for a sub article under the Wikipedia:Article series|article series guideline.  Ultimately, though, I think it's appropriate to delete for the following reasons
— NONE, NONE
