On March 21, 2026 we celebrate World Down Syndrome Day! This is a day to celebrate Down syndrome and raise awareness. There are many ways to get involved with the National Down Syndrome Society (NDSS) on World Down Syndrome Day (WDSD). Learn more about NDSS and WDSD.
Each year, NDSS partners with Down Syndrome International and Down’s Syndrome Association to encourage participation in World Down Syndrome Day globally. Every year, hundreds of individuals, professionals, researchers, and families from across the world gather to celebrate WDSD at the United Nations. The 2026 WDSD theme is Together Against Loneliness.
Use #WorldDownSyndromeDay to post on social media, and don’t forget to tag NDSS on Facebook, Instagram, LinkedIn, TikTok, and X so we can share your post.

"Just Evolve" Campaign
Every year, NDSS partners with CoorDown to present a video campaign in honor of World Down Syndrome Day. This year's campaign is titled, Just Evolve. This international awareness campaign is a call to action for all people, schools, organizations, companies, institutions, and the media to evolve our language around disability and commit to a full stop in using the R-word. Take action to eliminate the R-word from U.S. laws.
