Yeap, looks like it's for real. I'm all for having a день for Фаны to celebrate the Книги and/or JK Rowling, but 7 минуты of silence?!! I agree with cassie-1-2-3's
link on that one: it's disrespectful towards
real victims of tragedies and wars.
Something a bit еще Harry Potter related should have been picked to do on the day. I like how Фаны of Douglas Adams have Towel день - where Фаны are encouraged to carry a towel with them on the 25 of May, because according to the Hitchiker Книги a towel "is about the most massively useful thing an interstellar hitchhiker can have."
