When is National Smile Day?

National Smile Day is a holiday that was created to promote positivity and kindness through the power of a smile. It falls on May 31st every year, providing an opportunity for individuals to spread joy and happiness through simple gestures such as smiling at strangers or performing random acts of kindness.


History of National Smile Day
