Sultan's Birthday is observed in Brunei every July 15, celebrating the birth of Sultan Hassanal Bolkiah, who was born on July 15, 1946. The Sultan has been in power since October 4, 1967, following the abdication of his father, and his coronation took place on August 1, 1968, during Brunei's status as a British protectorate. The holiday highlights the Sultan's role as both the head of state and a religious leader, and it may be moved to August if it coincides with Ramadan. Under his leadership, significant developments in education and healthcare have occurred, including the establishment of educational institutions and the provision of free medical treatment for children and members of the Armed Forces. Sultan Hassanal Bolkiah is recognized as one of the wealthiest individuals globally, with a peak net worth estimated at US$200 billion in 2008. The celebration of this holiday reflects the cultural and historical significance of the Sultan's reign in Brunei.
