The Sultan of Terengganu’s Birthday is observed in Malaysia every April 26. This day marks the official birthday of the Sultan, Mizan Zainal Abidin, who became the 17th Sultan of Terengganu in 1998. The celebration is significant as it coincides with the anniversary of his installation as the 13th Yang di-Pertuan Agong, which took place on April 26, 2007. The Sultanate of Terengganu, established in 1724, has a rich history, having been ruled by various powers, including Thailand and the United Kingdom, before joining the Federation of Malaya in 1948. On this day, official events and ceremonies are likely held to honor the Sultan's contributions and leadership. Additionally, Terengganu also celebrates the Sultan's coronation anniversary on March 4.
