Southern Hemisphere Hoodie-Hoo Day is observed every August 22 in regions such as South America, Africa, and Australia. This unofficial holiday was created by the folks at wellcat.com as a way for people to celebrate and chase away the winter blues, particularly as August marks the last month of winter in the Southern Hemisphere. Participants are encouraged to go outside at noon, raise their heads above their heads, and shout "Hoodie-Hoo" as a ritual to welcome the arrival of spring. The term "Hoodie-Hoo" originates from the TV show The Andy Griffith Show, where it served as a greeting meaning "How are you?" This lighthearted celebration offers a fun way for individuals feeling weary of winter to engage in a communal expression of hope for warmer days ahead.
