Spongebob’s birthday is July 14, 1986

This is shown on SpongeBob’s driver’s license, which would make him 13 years old at the time of the show’s premiere. However, creator Stephen Hillenburg has gone on the record saying that SpongeBob has no real specific age – he is just old enough to live on his own and be going to boating school.

The character was originally intended to be named “SpongeBoy” – unfortunately this was already the name of a mop product!
