From 2023 onward, the King's Birthday has been marked on the Friday before the third Saturday in June. Although there has been no amendment to the Public Holidays Act to explicitly state this change, the pattern is evident in the annual government gazettes and supported by information from the relevant [Wikipedia entry](https://en.wikipedia.org/wiki/King's_Official_Birthday#Solomon_Islands). * There are a few exceptions to this rule: * [Queen's Birthday 2022](https://web.archive.org/web/20240727184251/https://solomons.gov.sb/wp-content/uploads/2022/05/Gaz-No.-171-Friday-27th-May-2022.pdf) * According to the holidays schedule for 2024, King's Birthday was celebrated on the 3rd saturday of June (June 15) and the preceding Friday was observed as a public holiday. * [King's Birthday 2025](https://web.archive.org/web/20250615054519/https://solomons.gov.sb/wp-content/uploads/2025/04/Gaz-No.-33-Wednesday-9th-April-2025.pdf) Province Days are not listed in the Public Holidays Act but are consistently announced in the official gazette each year. While the Public Holidays Act specifies the Sunday to next Monday observance rule, gazettes dating back to 2016 also follow the Saturday to previous Friday rule for shifting public holidays.
