December 14th marks an occasion that swings into the hearts of animal lovers and enthusiasts globally: Monkey Day. This unofficial international celebration, born out of the creative minds of Michigan State University art students Casey Sorrow and Eric Millikin in 2000, has evolved into a spirited recognition of primates and all things simian.

Initially conceived as a lighthearted nod to the primate kingdom, Monkey Day has transcended its humble beginnings on campus grounds to become a global affair. Sorrow and Millikin, both controversial artists at the time, never imagined their whimsical celebration would gain such widespread attention. Yet, their playful tribute to monkeys, apes, tarsiers, and lemurs has found a place in the hearts of people worldwide.

Throughout the years, Monkey Day has grown beyond its Michigan roots. It’s now hailed as World Monkey Day or International Monkey Day, celebrated in various ways across continents. From educational events highlighting primate conservation efforts to joyous festivities in zoos, museums, and online communities, the day fosters an appreciation for our primate relatives and raises awareness about their conservation needs.
