2011 Malaysia Day celebration at Merdeka Square, Kuala Lumpur
|Official name||Hari Malaysia|
|Significance||Marks the establishment of the Malaysian federation|
|Next time||16 September 2014|
Malaysia Day is held on 16 September every year to commemorate the establishment of the Malaysian federation on the same date in 1963. It marked the joining together of Malaya, North Borneo, Sarawak, and Singapore to form Malaysia.
The formation of the new federation was planned to occur on 1 June 1963, but was later postponed to 31 August 1963, to coincide with the sixth Hari Merdeka. Several issues related to objections of neighbouring Indonesia and the Philippines to the formation of Malaysia delayed the declaration to 16 September of the same year. The postponement was also done to allow the United Nations team time to conduct referendums in North Borneo (now Sabah) and Sarawak regarding the two states participation in a new federation.  The formation of Malaysia was made possible through the introduction of the Malaysia Bill to the Malayan Parliament on 9 July 1963, and consent from Tuanku Syed Putra, the Yang di-Pertuan Agong, on 29 August 1963.
Prior to the formation of Malaysia, Sarawak gained its transitional administration on 22 July 1963, while Singapore and North Borneo (which was renamed Sabah) began its transitional administration from the United Kingdom on 31 August 1963, thus coinciding with the sixth anniversary of the Malayan independence.
Since 2010, Malaysia Day has been a public holiday. Prime Minister Najib Razak made the decision after a question-and-answer session at Parliament on 19 October 2009, giving Malaysians have two celebrations related to the country's independence.
