October 7 – World Smile Day.

On World Smile Day, the theme is “Do an act of kindness.  Help one person smile!”  People worldwide embrace this theme and on WSD organize events and celebrations big and small, visible and unseen at their school, business, organization, community, or just within their family.  World Smile Day® Ambassadors also advocate for the day and help spread the word on social media and among their family and friends.
