The Sultan of Johor's Birthday is observed in Malaysia on March 23 every year as a public holiday in the state of Johor. This celebration commemorates the birthday of the incumbent Sultan, Ibrahim Ismail, who became Sultan in 2010 following the death of his father, Sultan Iskandar. The date was chosen to coincide with his coronation anniversary, which took place on March 23, 2015. The Johor Sultanate has a rich history dating back to its founding in 1528, and it was once a powerful empire that controlled significant territories. The holiday reflects the state's monarchical traditions, with various celebrations and events organized to honor the Sultan. Notably, the Sultan of Johor is unique among Malaysian sultans as he does not hold a university degree.
