What is World Down Syndrome Day?

World Down Syndrome Day is on 21 March every year. It is a global awareness day which has been officially observed by the United Nations since 2012. The goal is to help people understand and support those with Down syndrome better.

The date being the 21st day of the 3rd month was chosen to represent the triplication (trisomy) of the 21st chromosome which causes Down syndrome.
