North Borneo Self-Government Day is observed in Sabah, Malaysia, every August 31. This holiday commemorates the granting of self-government to British North Borneo in 1963, which occurred just weeks before the region united with the Federation of Malaya to form Malaysia. While most Malaysians celebrate Independence Day on the same date, citizens of Sabah view their self-government day as a more appropriate recognition of their historical context, as North Borneo was still a colony when the Federation of Malaya gained independence in 1957. Celebrations typically include parades, concerts, and various festive events, similar to those held for Malaysian Independence Day. The observance highlights the distinct historical journey of Sabah within the broader narrative of Malaysia's independence.
