World Smile Day® is celebrated on the first Friday in October.
World Smile Day® was created by Harvey Ball who claimed to be the creator of the Smiley Face®.
Harvey was concerned about commercialization of his Smiley Face®, so he created World Smile Day® to be celebrated from 1999 on.
The Harvey Ball World Smile Foundation was created to continue World Smile Day® after Harvey died in 2001.
Ironically enough, Harvey Ball did grab a lot of the credit for drawing the smiley face.
But he did not actually earn a lot from it’s popularity because he was not quick enough before quicker merchants ran with the happy face….and got the loot!
