3rd Day of the 3rd Full Week of the 3rd Month Each Year


National 3-D Day celebrates the art, science, and history of stereoscopic 3-D imagery. Every year, in March, on the third day of the third week of the third month, we explore the technologies used to create 3-D photographs, movies, and art, and we celebrate the many ways that these images have been viewed and enjoyed.

On Tuesday, March 21st, share your 3-D photos on social media, and when you do, be sure to use the tag #National3DDay

This year marks the 70th Anniversary of the many 3-D movies and 3-D comic books that came out in 1953. Celebrate on National 3-D Day by watching a classic 3-D movie, reading a vintage 3-D comic book, and sharing stories of your favorites with the world! Let's get 3-D trending on Instagram, Twitter, Facebook, TikTok, and Youtube and celebrate everything stereoscopic!

Everyone in the 3-D community at large is invited to participate in National 3-D Day and reach out to entertain, illuminate, and educate on the wide world of stereoscopic 3-D. From stereoview cards to 3-D comic books, lenticulars and holograms, 3-D movies to VR - share what you love with others. Stereo enthusiasts, clubs, and organizations around the world are encouraged to join in with their own events (done safely), online presentations, and pictures and videos shared on social media to make the day special.

Learn about the history of 3-D technology. Explore the science behind 3-D. Invite friends and family to watch a 3-D movie. Share your favorite 3-D experiences, whether they are movies, books, or art.


Share your own 3-D photos on social media, and when you do, be sure to use the tag #National3DDay



Founded by stereoscopic artist and researcher Ilicia Benoit, in collaboration with the501(c)3 nonprofit 3-D SPACE, National 3-D Day was registered with the National Day Calendar Registry in 2019, and the first celebration took place on March 17th, 2020.“Stereoscopy is indelibly marked into our physiology, as we not only sense the world around us visually, we are designed with a duality of two visual inputs- we are made to see this way. And we are able to imitate it in a multitude of ways and that is amazing. And the history of this language is only 180 years young! Every Invention, every discovery, every exploration matters, and 3-D Day was created to celebrate our devotions to it, and how it unites us all, and what we can learn from our collected histories.”
