The birthday of the Governor of Sarawak is a regional public holiday in Malaysia on the second Saturday in October.
The State of Sarawak is located on the north-west of the island of Borneo and is the largest of the 13 states by area.
The head of the Sarawak state is the Governor known as the Yang di-Pertua Negeri. The role is a largely symbolic position appointed by the King of Malaysia on the advice of the Malaysian federal government.
Abdul Taib Mahmud has been the Yang di-Pertua Negeri of Sarawak since 2014. Mahmud's birthday is on May 21st. As with many other states, the date of the official birthday doesn't change with each governor. In Sarawak, the second Saturday in October was chosen as it coincides with the first governor of Sarawak, Abang Haji Openg, whose birthday was October 7th.
