The date for World Down Syndrome Day is March 21, the 21st day of the 3rd month. It was selected to signify the 3 copies of the 21st chromosome which causes Down syndrome (Trisomy-21). Each year, it is a time to celebrate those with Down syndrome and to bring awareness worldwide that all people are all much more similar than any one of our differences. There are a lot of wonderful stories shared each year, and this year was no different. Here are some of our favorites from World Down Syndrome Day 2021.
