[Spongebob squarepants] How old was Spongebob at the beginning of the show?

* The first Spongebob episode premiered on May 1st, 1999
* An early episode had him show his drivers license, which listed his birthday as being July 14, 1986
* This would mean he is 13 years old at the start of the series.
* However, he is seemingly old enough to be living on his own and works a full-time job.

He's 30.
During the 14th episode of season one he travels exactly 2000 years into the future to the year 4017, meaning season 1 takes place in the march of 2017, making him 30  years old during season 1.
