The very notion of having a day to celebrate the Mad Hatter from Alice in Wonderland seems almost as mad as the man himself – yet here we are!

Today people across the globe will be donning orange wigs and top hats in a celebration of all that is silly.

How did the Mad Hatter get his name?

The Mad Hatter is actually just called the Hatter but everyone else refers to him as the Mad Hatter.

The phrase “mad as a hatter” dates back to the 18th century when mercury was used in the production of felt, which was then used to make hats.

Workers in the hat factories were exposed daily to trace amounts of the metal, causing some to develop dementia caused by mercury poisoning.

Consequently the phrase became popular as a way to refer to someone who was perceived as insane.

Why today?

Many versions of the zany character have him wearing a hat bearing a label reading “In This Style 10/6”.

This meant that a hat in that style cost 10 shillings and sixpence.

Daily Echo:

Inspiration is taken from this to act in the style of the Mad Hatter on 10/6 each year.

In the UK this would have been June 10, but as the day was founded in America it is October 6.

How did the day first come about?

IT workers in Boulder, CO, USA celebrated a day of tomfoolery in 1986 some computer-folk in Boulder, CO celebrated a general day of silliness, inspired by the character himself.
