Mad Hatter Day 

Mad Hatter Day is a great day to be silly and celebrate silliness. 

The Mad Hatter is a fictional cartoon character depicted in Alice's Adventures in Wonderland. The Mad Hatter is always acting silly. So, on Mad Hatter Day, it is only fair and fitting to act a little silly yourself. 
Despite being a silly day, the selection of the date was actually quite logical. The Mad Hatter wears a top hat. On the front of the hat is a slip of paper with '10/6' written on it. The paper is believed to be an order to make the hat, and that it costs ten shillings sixpence.
