​About World Down Syndrome Day! 

Each year on March 21st, we come together to celebrate World Down Syndrome Day, a day officially recognized by the United Nations in 2012. Here in Ontario, this special day is also celebrated as Ontario Down Syndrome Day, proclaimed in 2016. The date 03/21 holds particular significance, as it symbolizes the triplication of the 21st chromosome, a characteristic of Down syndrome, also known as Trisomy 21.

World Down Syndrome Day is a day to raise awareness, promote understanding, and show our support for individuals with Down syndrome. 
Join in the celebration and wear your most colorful, quirky socks! Let’s stand together to celebrate diversity and inclusivity. Share your photos on social media with the hashtag #WDSD to spread the love and raise awareness.
