World Down Syndrome Day 2026
March 21
About World Down Syndrome Day 2026
World Down Syndrome Day (also known as WDSD) is a global awareness initiative that has been backed by the United Nations since 2012.
It has been spearheaded by Down Syndrome International, which has linked up with national charities across the world to develop activities and events to raise awareness and support for those living with Down syndrome. It also highlights the facts of what it’s like to have Down syndrome, and how those with Down syndrome have, and continue to play, a vital role in our communities.
The date itself has been selected for very clever reasons; it is held on the 21st day of the 3rd month, which is a hat-tip to the uniqueness of the triplication of the 21st chromosome which leads to Down syndrome.
Let’s get people talking about WDSD on the 21st March! How? By wearing #LotsOfSocks!
…wear our official #LotsOfSocks socks, other brightly coloured socks, long socks, printed socks, 1 sock even 3 socks for 3 chromosomes. If you do not normally wear socks, then wear them. And why stop at socks? Wear our #LotsOfSocks t-shirts, WDSD t-shirts and other brightly coloured clothing.
