Mad Hatter Day
October 6, Monday

Origin of the holiday
Mad Hatter Day was first celebrated in 1986 in the USA. The idea was proposed by employees of a computer company who wanted to create a day for lighthearted madness and fun in the workplace. The date was chosen intentionally — in illustrations of Carroll’s book, the Mad Hatter’s hat shows a label with “10/6,” meaning 10 shillings and 6 pence, which also became a symbol of October 6 in the American date format.
