About Malaysia Day
Malaysia Day falls on September 16 and marks the formation of Malaysia in 1963. It is a national public holiday distinct from the August 31 National Day/Merdeka celebration.
The founding date is documented in records preserved by the National Archives of Malaysia and in the statutory chronology of the Malaysia Act 1963.
Why Malaysia Day matters
September 16 draws attention to the joining of Malaya, Sabah, Sarawak and Singapore in 1963 and to the federation's later constitutional history.
Regional experiences of federation, nationhood and identity should be discussed with sensitivity; public ceremonies do not erase different perspectives.
History of Malaysia Day
The National Archives of Malaysia records the signing of the Malaysia Agreement on July 9, 1963 and the formation proclamation on September 16, 1963, after the original August 31 target was postponed.
The federation originally included Singapore, which separated from Malaysia in August 1965; the founding composition and present federation should not be presented as identical.
Malaysia Day on September 16 is separate from Hari Merdeka on August 31, which commemorates the Federation of Malaya's 1957 independence.
