Monkey Day is celebrated internationally on December 14.
While the holiday is mainly about monkeys, it also celebrates other non-human primates such as apes, tarsiers, and lemurs.
Monkey Day was created and popularized by artists Casey Sorrow and Eric Millikin, in order to spread awareness for the animals, and to show love and care for them.
It is celebrated worldwide and often known as “World Monkey Day.”
The holiday was started in 2000 when artist Casey Sorrow, then an art student at Michigan State University, jokingly scribbled Monkey Day on a friend’s calendar, and then first celebrated the holiday with other MSU art students.
It gained notoriety when Sorrow and fellow MSU art student Eric Millikin began including Monkey Day in their artwork and Fetus-X comic strips, and began promoting it online along with other artists.
Since then, Monkey Day has been celebrated internationally, across countries such as the United States, Canada, Germany, India, Pakistan, Estonia, United Kingdom, and Colombia.
