Malaysia Day

Malaysia Day (Malay: Hari Malaysia) is a public holiday observed nationwide on 16 September each year since 2010. It marks the anniversary of the signing of the Malaysia Agreement, which came into effect on that date in 1963 and led to the creation of Malaysia. The agreement brought together the Malaya (independent since 1957), North Borneo (later renamed Sabah), Sarawak and Singapore into a single federation. Singapore was later expelled from the federation on 9 August 1965, and Malaysia Day is no longer observed there.

In East Malaysia, many regard Malaysia Day as the country's true "national day", arguing that 31 August commemorates the independence of Malaya, which was a separate political entity to Malaysia.
