World Down Syndrome Day (WDSD) is an opportunity to recognize and celebrate people with Down Syndrome around the globe. In 2012, the United Nations declared March 21st, the 21st day of the 3rd month of the year, as WDSD. This signifies the uniqueness of the triplication (trisomy) of the 21st chromosome which causes Down syndrome. This day was also declared Ontario Down Syndrome Day by the Legislative Assembly of Ontario in 2016.
Students & staff of St. Gregory the Great are encouraged to wear mismatched socks on March 21st as part of a world-wide theme for loving differences.
