Is there such a day as Harry Potter Day?

Yes, there is a so called Internation Harry Potter day that is also known as The Anniversery of The Battle of Hogwarts. That's on the 2nd of May, it's just happened.

There was a 7 minutes silence at 7pm to pay our respect to those who lost their lives fighting for what they believe in, good or bad.

I don't think their is one of Harry's birthday or any other occasion that I know of. Surely, if their was one, I'd put it on the day Harry Potter was first Published.

On 3rd December we celebrate the utimate Harry-Potter-Day to keep the magic around the boy who lived alive!
And: we want to get Potterheads connected!
If you want to participate draw the symbol of the Deathly Hallows (see the picture above) on your hand that day and let's see then if we probably meet someone that has done this too!

I am a big fan of Harry Potter
