Is Hermione Older or Younger than Harry?

So I've read the replies to the question, and I'm still bewildered.  
I would add on more comment to the mix.  Wouldn't Hermione have 
blurted out that she was younger than most students in the first 
scene with her on Hogwarts Express in Book 1 when she was nervously 
telling Harry and Ron how she had already read the text books and 
had done a little magic?

Of course, this assumes JKR was even aware of the issue.  I doubt if 
she expected her readers to pour over every detail and come up with 
every imaginable issue.
