This authority record treats the observance as a fixed annual date. The same month and day can be reused unless a stronger source changes the rule. Public-holiday or government status is never inferred from the observance name alone.
Overview
International Anti-Corruption Day is the United Nations observance on 9 December focused on corruption prevention, accountability, integrity and the role of the United Nations Convention against Corruption.
The day provides a public entry point into issues such as bribery, misuse of entrusted power, transparency, public institutions, private-sector integrity and international cooperation.
Why it matters
Anti-corruption work is broader than exposing individual scandals. Effective systems also depend on prevention, transparent procedures, independent oversight, reporting channels and fair enforcement.
Content about alleged corruption should distinguish verified findings from accusations. General observance material should not label a person or organization corrupt without authoritative evidence.
History
On 31 October 2003, the UN General Assembly adopted the United Nations Convention against Corruption through resolution 58/4.
The same resolution designated 9 December as International Anti-Corruption Day. The Convention entered into force in December 2005.
