[1] First launched in 1997 by the Ministry of Education in schools, the event commemorates the 1964 race riots which took place on 21 July 1964 when Singapore was still part of Malaysia (1963–1965) – 22 people lost their lives and hundreds were severely injured.

[3] On this day, students in schools across the nation are encouraged to be dressed in other cultures' traditional costumes such as the Cheongsam, the Baju Kurung, and Saree.

Traditional games such as five stones, zero points, and hopscotch are played, where inter-class competitions are sometimes organised.

In the week of 21 July, representatives from the Inter-Religious Harmony Circle (IRHC) comprising various religious groups also get together to pledge their support and to promote the Declaration.
