It appears that the date was used becuase of misinformation. I have removed the date as Patrick's birthday. However, I do have a hypothesis on the real date, which I believe to be December 14, but I would need that date to be confirmed by the staff on this. The date comes from the date that Patrick's identification card expires on, which in some places is the birthday of citizen who has it, but Bikini Bottom might not work that way, so I don't know.
