Malaysia Day (Malaysia)

Malaysia Day is a public holiday held on 16 September every year nationally since 2010 to commemorate the establishment of the Malaysian federation on that date in 1963. This event saw Malaya, North Borneo, Sarawak, and Singapore unite into a single state called Malaysia. Singapore, however, was expelled from the federation less than two years later, on 9 August 1965.

Malaysia is a country in Southeast Asia. A federal constitutional monarchy, it consists of 13 states and three federal territories, separated by the South China Sea into two regions: Peninsular Malaysia on the Indochinese Peninsula and East Malaysia on the island of Borneo. Peninsular Malaysia shares land and maritime borders with Thailand, as well as maritime borders with Singapore, Vietnam, and Indonesia; East Malaysia shares land borders with Brunei and Indonesia, and a maritime border with the Philippines and Vietnam. Kuala Lumpur is the country's national capital, largest city, and the seat of the legislative branch of the federal government, while Putrajaya is the federal administrative capital, representing the seat of both the executive branch and the judicial branch of the federal government. With a population of over 34 million, it is the world's 42nd-most populous country.
