What Is National Mad Hatter Day?
National Mad Hatter Day is an unofficial celebration based on the eccentric Hatter character from Lewis Carroll’s classic 1865 book, Alice’s Adventures in Wonderland.
People celebrate by wearing unusual hats, organizing tea parties, reading the book, solving riddles, dressing as Wonderland characters, or simply doing something creative.
There are no official rules for observing the day. The main purpose is to enjoy imagination and harmless silliness while celebrating a memorable character from classic literature.
Why Is National Mad Hatter Day on October 6?
The date has a connection to the Hatter’s hat.
In Sir John Tenniel’s illustrations for Alice’s Adventures in Wonderland, the Hatter wears a hat with a small label marked “10/6.”
The marking originally represented a price of 10 shillings and 6 pence, an amount in British currency at the time.
The numbers were later interpreted as 10/6, or October 6, using the month/day date format. This helped establish October 6 as the date associated with Mad Hatter Day.
Therefore, the date is not simply a random choice. It comes from a recognizable detail connected with the Hatter.
History of National Mad Hatter Day
The history of the character goes back to Alice’s Adventures in Wonderland, which Lewis Carroll published in 1865.
The book introduced readers to Alice and the strange world she discovers after falling down the rabbit hole. The Hatter is one of the unusual characters Alice encounters during her journey.
The modern celebration of Mad Hatter Day is generally traced to 1986, when computer technicians in Boulder, Colorado, reportedly created the observance as a playful occasion.
The celebration later became associated with October 6 because of the Hatter’s famous “10/6” hat marking.
Mad Hatter Day does not have the same formal history as an official national holiday. Its appeal comes from literature, popular culture, creativity, and the enduring popularity of Carroll’s story.

Who Is the Mad Hatter?
The Hatter is an eccentric character in Alice’s Adventures in Wonderland.
Alice encounters him at a strange tea party where she also meets the March Hare and the Dormouse. The conversation is filled with wordplay, unusual questions, riddles, and confusing ideas.
The Hatter is particularly associated with tea, time, riddles, and his unconventional behavior.
An interesting detail is that Carroll’s original text generally calls him “the Hatter” rather than “the Mad Hatter.” The longer name became widely associated with the character through later usage and adaptations.
His unusual personality makes him a natural symbol for a day that celebrates imagination and doing things differently.
Why Is the Hatter Called “Mad”?
The phrase “mad as a hatter” existed before Lewis Carroll wrote Alice’s Adventures in Wonderland.
The expression has often been associated with the historical use of mercury compounds in some hat-making processes. Long-term occupational exposure to mercury could cause serious neurological and behavioral effects.
However, the history of the expression is more complicated than simply saying that mercury created the phrase. The Hatter in Carroll’s story is a fictional character, and the book does not explain his behavior through mercury exposure.
The phrase and the fictional character became closely connected in popular culture over time.
What Does 10/6 Mean on the Mad Hatter’s Hat?
The 10/6 marking is one of the most recognizable details associated with the Hatter.
Originally, it referred to a price of 10 shillings and 6 pence for the hat.
Later, people connected the numbers with October 6 when read as a date. This became the basis for the date of National Mad Hatter Day.
The detail is a good example of how a small element from a classic book illustration can become part of a modern cultural celebration.
