The formation of the Federation of Malaysia was then announced on 16 September 1963, as Malaysia Day. The nationwide Independence Day celebration is still held on 31 August, the original independence date of Malaya, while Malaysia Day was a public holiday only in East Malaysia. However, this has caused some minor discontent among East Malaysians in particular since it has been argued that celebrating the national day on 31 August is too Malaya-centric. In 2009, it was decided that starting 2010, Malaysia Day would be a nationwide public holiday in addition to Hari Merdeka on 31 August.
