For some reason when I search up “When is Scratch's Birthday?” I always get different answers. “May 17th”, “May 3rd”, “May 6th” or “May 13th”. Which one is Scratch's real birthday?

15 May 2007 Is the first release of scratch.

So May 15th? If so, how come this year they are celebrating on May 10th?

Probably because of the ST's schedule or something. It's close enough that most scratchers won't care.

That makes sense, Ty!
