World Down Syndrome Day
March 21
World Down Syndrome Day (WDSD) is marked each year on March 21,[1] beginning in 2006. The 21st day of March (the 3rd month of the year) was selected to signify the uniqueness of the triplication (trisomy) of the 21st chromosome which causes Down syndrome.
Every year on March 21, World Down Syndrome Day is observed to create awareness about Down syndrome. A common activity is wearing colorful or mismatched socks, to show support for people with Down syndrome because socks are shaped somewhat like chromosomes.
Join our Do Better. movement for the month of March as we celebrate World Down Syndrome Day on March 21.
