WHY MARCH 21 MATTERS

3/21 is a number with a story.

March 21 is World Down Syndrome Day. The date, 3/21, stands for the three copies of chromosome 21 associated with Down syndrome.

Celebrate 3.21 is about awareness, celebrating differences and building a more inclusive community. Families matter most here, because kindness and inclusion often begin at home.

LITTLE MOMENTS, BIG MEANING

Small things count.

A few ways families join in. Your personal ideas live in Find Your Family’s Extra above.

  • Wear colorful socks

    Odd, bright, mismatched. Then tell someone why.

  • Read together

    Pick a story about belonging and talk about it.

  • Make something

    A window sign, a card, a decorated sock.

  • Spread kindness

    Invite someone to play. Say hello first.
