National Day in Brunei is observed every February 23, celebrating the country's independence from the United Kingdom, which officially occurred on January 1, 1984. The European presence in Brunei began in the 16th century, leading to British intervention and the signing of the Treaty of Protection in 1888, which placed Brunei under British protection. The decolonization process extended into the early 1980s, culminating in the proclamation of independence by His Majesty Hassanal Bolkiah at midnight on January 1, 1984. While the official independence date is January 1, the National Day celebration is held on February 23, marking the significance of this transition in Brunei's history. This day is a public holiday, reflecting national pride and the country's journey toward self-governance.
