March 21 is World Down Syndrome Day.
The date represents the triplication of the 21st chromosome, which is what causes Down syndrome. This day is recognized around the world to raise awareness and promote the rights, inclusion, and well-being of people with Down syndrome.
At Y.E.S. The Arc, we believe every person deserves respect, opportunity, and the ability to fully participate in their community. Today we celebrate the contributions, talents, and voices of individuals with Down syndrome and the families and advocates who support them.
Together, we can continue building communities where everyone is valued and included.
