Dates and calendars in Potterverse

No: HPFGUIDX 97511

With all these people trying to discern exactly when things happened by what the night sky 
looked like, and whether or not Lupin's full moon was on schedule for 1995, and just what 
date was the Forbidden Forest detention (Mars is bright tonight), and all that, I have just one 
question for you.  I hope it doesn't sound offensive -- I'm really not trying to insult anyone, 
I'm just really, truly, honestly, and thoroughly curious!

How do you expect to reconcile literary astronomical indicators to real world dates when, for 
five years now, September first has been a Sunday?  Doesn't that just scream out that JKR 
is not using a real world calendar?
