F&WF 2015 dates?

[Squggl3]

Hello! I am looking for the starting date of the f&wf for 2015 online I read sept. 18 so I planned a trip for the 12-20 but Birnbaums 2015 book says the first day is sept. 25th. Which means I would have to go from the 19-27th anyone have more info?! Should I trust Birnbaums?

That's when it normally opens but this year they extended it a week so it actually opened a week earlier than normal. I'm not sure 2015 dates are officially released or not but its always around the same time frame

I just want the majority of my trip before f&wf but would like a couple days of the festival. But I can always change the dates later
