International Rock Flipping Day is observed on the third Sunday of September each year. It is a day to encourage people to explore and learn about the natural world by flipping over rocks to see what creatures and other organisms live underneath them. Participants share their findings and observations with others to promote curiosity and appreciation for the environment.
