World Down Syndrome Day (WDSD) is observed on March 21.
On this day, people with Down syndrome and those who live and work with them throughout the world organize and participate in activities and events to raise public awareness and create a single global voice for advocating for the rights, inclusion and well being of people with Down syndrome. Many of these events are recorded on the official World Down Syndrome Day website, http://www.worlddownsyndromeday.org.
