CHANDLER, Ariz. -- Although it's a unique sequence on the calendar, Dec. 12 is just another day for most people. But it's a special day for a student at Aprende Middle School in Chandler. Caleb Castillo got a surprise visit from Gibby Parra and 3TV -- and the camera was rolling.

Caleb is celebrating his 12th birthday. In fact, 12s are wild for Caleb. He was even born during the 12 o'clock hour -- 12:11 to be exact. 

But as Caleb sat in Mrs. Gibbs' science class this morning, he had no idea what he was in for.
