Quick Fact

National Black Cow Day celebrates the classic root beer float made with vanilla ice cream and root beer, known as a 'black cow.' The treat reportedly originated in Colorado in the 1890s when a man named Frank J. Wisner added a scoop of ice cream to his root beer, inspired by the snow-capped mountains outside his window.

Origins and Establishment of National Black Cow Day

The exact origins of National Black Cow Day are unclear, but it is believed to have been created in the early 20th century to honor the root beer float. The treat itself dates back to 1893 when Frank J. Wisner of Cripple Creek, Colorado, supposedly added a scoop of vanilla ice cream to his root beer, naming it the 'Black Cow' after the dark beverage and white ice cream resembling a cow. The holiday gained official recognition through the National Day Calendar in the 2010s, though it may have been celebrated informally for decades.

Over the years, National Black Cow Day has evolved from a local celebration into a nationwide event. It is observed annually on June 5th, with ice cream parlors, diners, and home cooks promoting the classic float.
