Down Syndrome International (DSI) has officially earmarked 21 March as World Down Syndrome Day (WDSD). The date was chosen to signify the uniqueness of Down syndrome in the triplication (trisomy) of the 21st chromosome and is used synonymously with Down syndrome.
Singapore was selected to launch the inaugural WDSD in 2006. The event, held at the CHIJ Secondary School in Toa Payoh, in the heartlands of Singapore was very successful and well attended. Many other organisations worldwide joined in the celebrations with events and activities in their respective countries.
This year the theme for 21 March 2008 is "Aim High Enough", to continue creating awareness about Down syndrome and promote acceptance of diversity.
