World Smile Day® is celebrated on the first Friday in the month of October every year. The idea of was coined and initiated by Harvey Ball, a commercial artist from Worcester, Massachusetts. He is known to have created the Smiley Face in 1963.[1] The World's first World Smile Day was held in the year 1999 and has been held annually since.
After Harvey died in 2001, the Harvey Ball World Smile Foundation was created to honor his name and memory, with the slogan "improving this world, one smile at a time." The Foundation continues as the official sponsor of World Smile Day® each year.
The organization states that their goal is to "make as many people as possible aware of World Smile Day® by using the web, social media, and your help to encourage smiles and acts of kindness around the world."
