World Down Syndrome Day
What is World Down Syndrome Day (3/21)?
World Down Syndrome Day (WDSD) is a global awareness day celebrated each year on March 21. This date signifies the uniqueness of the triplication (trisomy) of the 21st chromosome, which causes Down syndrome. On this day, individuals and organizations worldwide come together to celebrate the lives of people with Down syndrome, promote inclusion, and advocate for their rights and well-being.
How can you show your support on WDSD?
There are many ways you can participate in World Down Syndrome Day! From showing off colorful socks, using your own voice and platform to advocate, and participating in local events, you can help create a more accepting and inclusive world. Here are a few ways that you can join DSDN on that day.

Why is 3/21 significant to DSDN?
In addition to spreading awareness and advocating on WDSD, the Down Syndrome Diagnosis Network (DSDN) was founded on World Down Syndrome Day in 2014 with a mission to support families receiving a Down syndrome diagnosis. Through our community-driven approach, we connect expectant and new parents — and the medical professionals who serve them — with resources, information, and a network of support. From personalized online groups to our annual Rockin’ Mom® and Rockin’ Dad™ Retreats, DSDN fosters a community where parents can find understanding, connection, and empowerment.
