This article is about the mainstream, New Earth version. So only information from after 1986 counts, the rest is Earth-Two or Earth-One. Also The Dark Knight Rises takes place on Earth-31 - it's not canon either.

And "Batman 337 to 570" covers 17 years of Batman comics. It's about as specific as "it's in the Bible, somewhere".
