International Sloth Day is celebrated annually on Oct. 20 to honor and recognize the slow-moving mammals. 

The day was created by the foundation AIUNAU "as a compromise acquired on the first Sloth International Meeting about the wellbeing and conservation of sloths" in November 2010.

You can observe this day by attending special presentations held at several zoos or by donating money to a wildlife organization working to protect sloths
