On comic pages, there are two things which says when a comic is released, like on, it says the release date is 2nd of January, 2013; while it also says it's "Published" March, 2013.

What is it that determines when a comic's been "published"? And how can a comic that's already been released have a publishing date two months ahead? This has boggled my mind ever since I joined both this and the DC wiki.
