Why did James Cameron chose the date August 24th as the birthdate for the Avatar (on the computer screen in the last scene)?

I have no idea. It could be just a date picked at random. Could be someone's real birthday that the cast or the director know. Who knows.

Im not sure but maybe it was the day in 1994 when James Cameran came up with the idea of Avatar, Maybe he had a dream about it or somethin...Dunno*
