World Down Syndrome Day

World Down Syndrome Day – annually on March 21st – is officially ratified by the United Nations. It allows communities around the world to recognize and celebrate contributions from people with Down syndrome.



World Down Syndrome Day (WDSD) is Saturday March 21, 2020.  We encourage raising awareness about Down syndrome in your school and in the community and we appreciate your support.

The Canadian Down Syndrome Society has developed a WDSD Celebration Kit, and we have some great tools for your classroom, community, or event!

  • Wear #LotsOfSocks!

Ask your students to wear colorful, fun socks on WDSD, it helps to raise awareness and puts some fun into the celebrations!

  • Share your celebrations!

Share your group pics with us at @CdnDownSyndrome on Twitter, Instagram and Facebook.  Use #SeeTheAbility #WDSD20 #WorldDownSyndromeDay
Please respect privacy when sharing images, especially photos with minors. Please follow your school or groups approval policies prior to sharing on social media.

  • Get out in your community!

Ask a self-advocate role model in your community to speak to your community group or class. Set up a display or information booth! Do this at your local mall, school or library. Talk to local newspapers or local media personalities!

  • Look for Lights!

On the evening of March 21, ask your students to keep their eyes open for landmarks around the city and across the country that are lit up in blue and yellow to recognize this important day.

CDSS is a nonprofit organization dedicated to raising awareness and providing information on Down syndrome and all the life stages.
