Mad Hatter Day

Whether or not you are aware of such an occasion - yes we do live in a world crazy enough to celebrate such a day.

In parts of the world it is celebrated on October 6 and in Britain they celebrate it on June 10. Both dates were chosen from the illustrations by John Tenniel in Alice's Adventures in Wonderland, depicting the Mad Hatter wearing a hat bearing a slip of paper with the notation "In this style 10/6."
