The birthday of the Yang di-Pertuan Agong is observed in Malaysia every first Monday of June as an official public holiday. This day celebrates the elected monarch of Malaysia, who is formally chosen for a five-year term from the nine hereditary royal rulers of the Malay states. The title of Yang di-Pertuan Agong was introduced in 1957, with Tuanku Abdil Rahman being the first to hold the position. The celebration is marked by various festive events and ceremonies across the country, with the most notable festivities taking place in Kuala Lumpur, the federal capital. These celebrations typically include a military parade and performances by military bands, reflecting the ceremonial nature of the holiday.
