Vesak day in the context of "Nibbāna"

Among religions in Brunei, Sunni Islam is predominant. In 2021, the government census showed that 82.1% of Brunei's population is Muslim. However, other religions also have a considerable foothold in Brunei: 6.7% of the population is Christian and another 6.3% is Buddhist. The remaining 4.9% subscribe to various religions, including indigenous religions.

Islam is the state religion of Brunei. Freedom of religion and the right to practice privately are nominally guaranteed. Furthermore, some non-Islamic holidays, such as Lunar New Year, Christmas, Vesak day and Gawai Dayak, are recognised. These rights, however, are limited in practice: religious education is controlled, even in the Chinese, Christian and private schools. Brunei's penal code criminalizes efforts to promote religions other than Islam to Muslims or the non-religious, including persuading religious conversion, exposing Muslim children to other faiths, or opposing Islamic authorities. It also punishes those who assist in such acts. These provisions marginalize non-Muslims and non-believers, severely restricting their religious freedom in violation of international human rights standards. Non-Muslims must be at least 14 years and 7 months old if they want to convert to another religion. A minor will automatically become a Muslim if their parents convert to Islam.
