World Smile Day History

World Smile Day is dedicated to spreading happiness and goodwill through the simple act of smiling. It originated from the iconic smiley face, created by American commercial artist Harvey Ball in 1963. Ball intended the symbol to represent pure happiness, free from any political or religious associations. He later established World Smile Day to combat the increasing commercialisation of his creation and to remind people of its original, positive message. The day encourages acts of kindness and aims to foster a global sense of cheerfulness.

The concept of World Smile Day was conceived in the 1990s by Harvey Ball, who felt his iconic smiley face had lost its intended meaning due to commercialisation. He established the day in 1999, with the first official celebration taking place in 2000.
