World Down Syndrome Day
21 March 2026
In December 2011, the UN declared March 21 as the World Down Syndrome Day, to be observed annually starting in 2012. The General Assembly invited all member states, relevant UN institutions, international organizations, and civil society, including non-governmental organizations and the private sector, to observe the World Down Syndrome Day to raise public awareness of the Down syndrome.
The events held on this day aim to improve the quality of life for individuals with Down syndrome by meeting their needs, including providing healthcare, conducting regular medical check-ups to monitor mental and physical development, and offering timely interventions such as physical therapy, counseling, or special education.
