Hello and a Question regarding Bk 7

Hello all!  It's been a looong time since I visited this site, but I 
figured I'd give you all a try out, since I haven't really been 
discussing things lately.

In the HP Lexicon, it states some theories about book 7.  One of the 
things mentioned is that the events of this book will take place 
between July 31, 1997 and the end of the following school year, 
presumably, June 1998.  Also, Harry must return to the Durselys' one 
more time before his 17 birthday, and he will be attending Bill and 
Fleur's wedding in July.

Now; if book 7 events won't start till July 31, how in the world is 
he going to attend the wedding?  I guess we won't see that??  

And, how does one know that book 7 won'd start till after July 31?  
Is this a guess?

The reason I'm asking is that I'm writing a short peice starting 
after HBP, and I'm curious to know/ guess how long Harry will be at 
the Durselys', before he leaves for good.  

Does anyone know when school ends in June?  I've looked and looked, 
and perhaps not looked in the right places but I can't find anything 
definitive.

Any help, much appreciated.
