Fun Holiday – Mad Hatter Day

The unofficial holiday was created in 1986 in Boulder Colorado by a group of computer technicians who were inspired by the Hatter and his antics in the epic fantasy novel.

In the book, the Hatter is an eccentric milliner for whom time is forever stuck at a tea party with his friend the March Hare.


The date for the holiday was chosen because of how John Tenniel illustrated the Hatter in Alice in Wonderland. The English illustrator who was also a political cartoonist depicted the Hatter wearing a hat with a piece of paper that has 10/6 written on it. The 10/6 refers to the cost of a hat – 10 shillings and 6 pence. The creators of the holiday who are from the United States where the date is written in the month/day (mm/dd) format took this to set the date for the holiday on October 6 (10/6). For those who write the date in the day/ month (dd/mm) format, the holiday would fall on June 10.
