When's spongebobs b-day?

I know the EXACT date of his birth. In one of the episode, he has a dream he gets his license and the license shows all his information about his birth and area of birth. His birthday says July 14,1986 which means he is 24 years old now. But he acts like a kid. The show wants kids to think he is a kid but he is really an adult, but doesnt act like one. This is his official birthday, so he is 24 years old.
