Preparing for World Down Syndrome Day (March 21)

World Down Syndrome Day (WDSD), observed every March 21, is a global celebration and awareness day recognized by the United Nations since 2012. The date—3/21—was chosen to symbolize the triplication (trisomy) of the 21st chromosome, which causes Down syndrome. The purpose of WDSD is to educate, advocate, and celebrate the unique abilities and contributions of individuals with Down syndrome, while promoting inclusion and challenging stereotypes.

Start with Awareness and Education
Begin preparations by sharing information about Down syndrome with your school or community. Use resources like presentations, posters, and videos to explain what Down syndrome is and highlight that people with Down syndrome are more alike than different. Consider reading books featuring characters with Down syndrome, such as “47 Strings: Tessa’s Special Code” or “My Friend Isabelle,” and hosting story times or discussions about acceptance and diversity.

Embrace the “Lots of Socks” Campaign
One of the most recognizable ways to celebrate is the “Lots of Socks” campaign. Encourage everyone to wear colorful, mismatched socks on March 21 to symbolize the uniqueness of individuals with Down syndrome. Share photos on social media using hashtags like #LotsOfSocks and #WorldDownSyndromeDay to spread awareness and foster a sense of community.

Plan Inclusive and Creative Activities
Organize activities that involve everyone and celebrate inclusion. Ideas include:

• Hosting a “21 Challenge,” where participants do something themed around the number 21—like 21 acts of kindness, 21 jumping jacks, or sharing 21 facts about Down syndrome.

• Creating a schoolwide banner or bulletin board about WDSD, or setting up an art exhibition featuring works by individuals with Down syndrome.

• Running a “Rock Your Socks” day, sock puppet workshops, or a sock drive for charity.

• Inviting guest speakers, including self-advocates with Down syndrome, to share their stories and answer questions.

Promote Advocacy and Self-Expression
WDSD is also about advocacy—supporting the rights, inclusion, and well-being of people with Down syndrome. Encourage students and community members to speak up, share personal stories, and participate in campaigns that challenge stereotypes and promote acceptance. The 2024 theme, “End the Stereotypes,” is a reminder to focus on abilities, not limitations.

Extend the Celebration Beyond One Day
While March 21 is the focal point, use this time to start ongoing conversations about diversity, equity, and inclusion. Provide resources for teachers and families, such as coloring sheets, activity guides, and recommendations for inclusive education practices. Consider organizing a kindness week, inclusive sports events, or ongoing classroom lessons about neurodiversity.

Connect with the Global Community
Join the worldwide movement by participating in virtual events, sharing stories and photos online, and connecting with local Down syndrome organizations for additional support and resources. Every act—big or small—helps build a more inclusive and understanding world.

By planning early and intentionally, you can make World Down Syndrome Day a meaningful, joyful, and impactful celebration for your classroom, school, or community—one that honors the achievements, rights, and voices of individuals with Down syndrome all year long.
