Malaysia Day (Malay: Hari Malaysia; Jawi: هاري مليسيا‎) is a public holiday held on 16 September every year to commemorate the establishment of the Malaysian federation on that date in 1963. This event saw Malaya, North Borneo (which was renamed Sabah), Sarawak, and Singapore unite into a single state. Singapore, however, was expelled from the federation less than two years later, on 9 August 1965.
