Independence Day (Malaysia)

Independence Day (Malay: Hari Merdeka), also known as National Day (Malay: Hari Kebangsaan), is the independence day of the Federation of Malaya from the United Kingdom. It commemorates the Malayan Declaration of Independence of 31 August 1957, and is defined in article 160 of the Constitution of Malaysia. The day is marked by official and unofficial ceremonies and observances across the country.

The observation of 31 August as Malaysia's national day is the cause of some controversy, especially among East Malaysians, with calls to prioritise the celebration of Malaysia Day (Hari Malaysia) on 16 September instead. Malaysia Day commemorates the formation of Malaysia in 1963, when the four entities of North Borneo, Sarawak, Singapore and Malaya federated to form Malaysia as part of the Malaysia Agreement.

East Malaysians argue that it is illogical to celebrate 31 August 1957 as Malaysia's national day when Malaysia was only established in 1963, and that the "Federation of Malaya" was a different entity. Supporters of Hari Merdeka argue that "the Federation" as defined in article 160 of the Malaysian constitution is the same "Federation of Malaya" that was first established in 1948 and when it ceased to be a British protectorate on 31 August 1957.
