Unfortunately the software does not do it Massive overlinking of dates throughout Wikipedia has meant that readers have no way of knowing which of the many links on a page contain useful information If it is not possible for a reader to discriminate it is difficult to define rules for software I do not agree that the 1117 link is useful but you have suggested a clear rule I think that you are proposing a rule that is clear 1 Look at ArticleA 2 Look inside the article for year link e g ArticleB ArticleC etc 3 Go to ArticleB and looks at What links here 4 Check if What links here of ArticleB contains ArticleA 5 Use that information to modify the delinking rule I do not know how to do it The date delinking regex is published in the talk page so you can see what it does Feel free to suggest modifications Thanks
