Release date for Harry Potter movie - was it changed?

[Tonks]

I called the local theater and they said the date was changed to the 
11th or something. I think that I just got the village idiot. Does 
anyone know the truth about this? It is still the 13th??? or what???

I am trying to send out anouncements for a movie party, but can't find 
the correct time and day by calling (duh...) the theater. You would 
think that they would know!
