International Whisk(e)y Day is observed worldwide every March 27, celebrating both whiskey and whisky. Established in 2009, this holiday commemorates the birthday of the influential English writer Michael Jackson, known for his significant contributions to literature on beer and whiskey. The inaugural Whiskey Day Festival took place in the Northern Netherlands, featuring several whiskey writers to honor Jackson. The day is not organized by any specific entity but is celebrated by activists and enthusiasts of whiskey and whisky, which include Scottish, Canadian, Japanese, American, and Irish varieties. There is a notable distinction between International Whisk(e)y Day and World Whisky Day, as both holidays occur on different dates, with the founders of International Whisk(e)y Day aiming to avoid being seen as a copycat event.
