When is National Smile Day?
Every year on May 31.
What is National Smile Day?
National Smile Day on May 31 was established in 2018 by dentists Dr. Tim Stirneman and Jim Wojdyla to celebrate the power of a smile. Science backs it up: smiling releases endorphins, reduces stress, and can even lower blood pressure. Today, share your smile with the world.
How to celebrate
Mark the day with a poster made in Dayfeed — pick your favourite photo as the background, share it to your story or group chat, and set a reminder so you never miss it next year.
