What is World Down Syndrome Day (WDSD)

March 21st is a global day of celebration and awareness that has been observed by the United Nations since 2012. It’s purpose is to educate the world on what Down syndrome is and how individuals with Down syndrome need to be valued in their communities. The date for WDSD symbolizes the 21st day of the 3rd month, which was selected to signify the triplication (trisomy) of the 21st chromosome which is Down syndrome. 

About Down Syndrome

Down syndrome is one of the most common genetic variations and occurs in approximately one in every 700 live births in the United States. It is a naturally occurring chromosomal arrangement, being present across racial, gender or socioeconomic lines. According to the CDC, there are three types of Down syndrome: Trisomy 21, Translocation Down syndrome, and Mosaic Down syndrome. Learn more about Down syndrome. 

Get Involved

WDSD is a great opportunity to spread awareness!  Each year, in our little corner of the world, we are proud to celebrate our community and to do our part to spread awareness, acceptance and inclusion. Here are some ways that we celebrate every year…

Rock Your Socks Campaign

The Rock Your Socks campaign exists to raise awareness of Down syndrome.  Choose your socks to get noticed and get your family, friends, classmates and colleagues to join in on the fun! 

Color it Blue+Yellow!

Every year, working with the Commonwealth of MA, the landmark Leonard Zakim Bunker Hill Memorial Bridge is lit up blue + yellow – the colors of Down syndrome!

You can join too by helping us light something blue+yellow on 3/21. Ask your local churches, synagogues and mosques; stores; venues to light it up blue+yellow. Put blue+yellow candles in your windows. Put blue+yellow lights around your house. Paint your nails blue+yellow. Be creative. Have fun!
