Clouds birthday?

[Croyles]

Ok as much as it doesnt matter when Clouds birthday is im still gonna get to the bottom of this.

Both the english and japanese official websites say his birthday is on the 11th of august, but his original birthdate was on the 19th, which was clearly stated in the FFVII manual. Now either square have for some reason decided to change his birthday, he found out his real birthday along with his real identity, or it started out as a minor typo mistaking 9 with 1, which caused the japanese website to say it was on the 11th, and seeing as how the english website seems like a straight copy of the japanese one considering its style of flashy rotating pictures etc, the english website just copied that info and has now caused EoFF to have a long thread on that topic. So, which theory seems the most realistic one?
