The origins of Malaysia Day stem from the fact that September 16, 1963, marked the founding of the Federation of Malaysia, comprising Malaya, Sabah, Sarawak, and Singapore. Since 2010, this day has been designated a national public holiday in Malaysia to strengthen unity and identity between East and West Malaysia.

Historical Background
September 16, 1963
The Federation of Malaysia was officially established, comprising the former Federation of Malaya, North Borneo (present-day Sabah), Sarawak, and Singapore (Singapore later gained independence in 1965).

The difference between "National Day" and "Malaysia Day"
Malaysia's Independence Day is August 31, commemorating the independence of the Federation of Malaya in 1957. Malaysia Day, on September 16, commemorates the significant event of the formation of the entire Federation in 1963.

Becoming a public holiday
To further strengthen national identity, particularly the connection between East and West Malaysia, the Malaysian government designated September 16 a national public holiday in 2010.

Meaning
Promoting Unity
As a public holiday, Malaysia Day helps foster understanding, unity, and identity among the country's diverse regions.

Commemorating History
