INTERNATIONAL DAYANIMALS

International Sloth Day

Every year on the third Saturday in October, the world slows down for International Sloth Day. Founded in 2010 by the Colombian wildlife foundation AIUNAU, this delightfully unhurried holiday celebrates the adorable tree-huggers of Central and South America and the rainforests they call home. Warning: celebrating may cause extreme relaxation.

3 ways to celebrate

AT HOME

Take a gloriously slow afternoon

Cancel one errand, take a nap, or go for a slow phone-free nature walk. Move at sloth pace for at least part of the day.

IN THE COMMUNITY

Donate to sloth conservation

Give to a rescue and rehabilitation group like AIUNAU or The Sloth Institute, and spread the word that sloths do not make good pets.

WITH FRIENDS

Watch a sloth documentary with the kids

Learn about the six sloth species together and share your favorite sloth fact, like the algae camouflage in their fur.
