Perhaps, not many who know that, today, 16th of September is Malaysia Day, the day Malaysia was formed. The Malaysia day is very significant although it's not really well known as compared to the Merdeka Day.
Malaysia day is the day to commemorate the formation of the establishment Malaysian Federation on 16th of September 1963. On this day, Malaya, North Borneo (now Sabah), Sarawak, and Singapore (Singapore left Malaysia in 9th of August 1965 to form a new state) joined together to form Malaysia. From this day onwards, Malaya was known as Malaysia.
At first, the formation of Malaysia was arranged to be on 1st of June 1963 but was later postponed to 31st of August 1963 so that it would coincide with the 6th Merdeka Day.

The postponement to 16th was also to allow the United Nations (UN) to conduct the referendums in North Borneo and Sarawak regarding the 2 states participation in the Federation of Malaysia.
