Hello!

This is something that's been bugging me for a while.  I search to 
see if there was something similar but I couldn't find it.  
When is Ginny's birthday?  I know we don't know, but an aproximate of 
it.

We know March 1 is Ron's Birthday.  And somebody said it was 1980 the 
year????  But when would it be aproximate time for her. 

Someone told me that in some Spanish place JKR said it was Oct. 
31???? 

Does anybod have any idea that can give me a little help.  I'm rather 
bad at numbers.


Thanks   

Gily Ann
