Bison-ten Yell Day

Bison-ten Yell Day, celebrated annually on September 2nd, is one of the more curious holidays with a playful twist on linguistics. It may seem like a whimsical day without much reason, but it has its quirky appeal, mainly due to the phonetic playfulness of its name, which sounds like “bicentennial” when repeated.


The holiday originated as a humorous celebration, but it also nods to historical forms of communication. The name “Bison-ten Yell” is believed to be a pun on “bicentennial,” yet the day also commemorates the invention of military signals, where each signal corresponded to a specific word, facilitating efficient communication. The “ten Yell” part likely refers to the original set of ten signals used in military communication.
