The Sultan of Pahang's Birthday is observed in Malaysia every July 30. This holiday celebrates the birthday of the Sultan, who is the head of the state of Pahang, the third largest state in Malaysia by area. The origins of Pahang date back to its establishment as a kingdom and later as a vassal sultanate of Malacca in the 15th century. The current Sultan, Abdullah, ascended the throne in January 2019, and the celebration was moved to July 30 from October 24, the date previously observed during the reign of his predecessor, Sultan Ahmad Shah. The day is marked by various festivities and events that honor the Sultan's contributions and leadership.
