Today is Malaysia Day, it is a holiday. In 1963 16th of September, Sabah, Sarawak (and Singapore) join Malaya and form Malaysia.
(Singapore separated from Malaysia since 1965)
There are people arguing, should National Day be the 31 August Merdeka Day or the 16 September when east and west Malaysia united together.
For me it doesn't matter, as long as everyone can access to the Internet happily, that's call united.
