Every year on March 21st, we celebrate World Down Syndrome Day! This is a special day when the whole world talks about love, friendship, and acceptance of people with Down syndrome.
What is Down syndrome?
Down syndrome is something some people are born with. It means they have one extra chromosome in every cell of their body that decides how we look and how our body works.
People usually have 46 chromosomes in every cell of their body, arranged in 23 pairs. But people with Down syndrome have one extra chromosome on the 21st pair — instead of two, they have three chromosomes on the 21st pair. That’s why March 21st (3/21) was chosen as their special day — because the numbers 21 and 3 represent their three chromosomes.
People with Down syndrome are unique and special, just like all of us! They can go to school, learn new things, play, sing, dance, and dream big dreams.
Why do we wear colorful socks on World Down Syndrome Day?
On this day, many people wear colorful and mismatched socks because socks that don’t look the same symbolize diversity — and diversity is what makes the world more beautiful!
You can participate too. Just pick two fun socks that don’t match and wear them proudly on this day. This way, you show support for friends with Down syndrome and believe that all people deserve love and respect.
