Mad Hatter Day
Celebrate Mad Hatter Day! The Mad Hatter is a famous character in Lewis Caroll’s book Alice's Adventures in Wonderland. Today is all about embracing his absurdity.
In 1986, a group of computer technicians in Boulder, Colorado celebrated the first Mad Hatter Day. They designated the holiday as a day of silliness and year after year it has grown in popularity. Mad Hatter Day is celebrated each year on October 6 because the Mad Hatter wears a top hat labeled “In this style 10/6” in the book’s illustrations. It is also six months from April Fools’ Day, the first silly holiday of the year.
Today, recognize the reality that is nonsense and the silliness that is sane. Grab a top hat and celebrate a very merry Mad Hatter Day!
