The notoriety of the Ides of March has left many with the impression that the Ides invariably fall on the 15th. I wouldn't bother with nyah-nyahing the editors of Fortune but I would expect better of Anu.

Another potentially interesting question is whether the "Beware the Ides of March" line predates Shakespeare. I have nothing more than a vague felling that legend says that he was warned, possibly by that classic oxymoron, the blind seer.
