World Down Syndrome Day

Description

World Down Syndrome Day is observed on 21 March each year. The date (the 21st day of the 3rd month) signifies the triplication of the 21st chromosome, which causes Down syndrome. The 2026 theme is "Together Against Loneliness", highlighting that 39% of people with intellectual disabilities often feel lonely, compared to 14% of the general population. The campaign calls for real inclusion in schools, workplaces, and communities. For digital accessibility, this underscores the need for clear, simple interfaces, easy-to-read content, consistent navigation, and inclusive design that supports people with cognitive and intellectual disabilities.
