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

The authority record classifies it as fixed annual, so its month and day are reusable unless stronger evidence changes the rule.

Is International Anti-Corruption Day an official public holiday?

Who established or recognizes International Anti-Corruption Day?

The reviewed provenance layer identifies United Nations General Assembly as the proclaiming or establishing body.

Is International Anti-Corruption Day international or country-specific?

The record has international or global institutional scope: United Nations / international observance. That does not mean every country treats the date as a public holiday or observes it in the same way.

Why is International Anti-Corruption Day on 9 December?

Did the day come before the UN Convention against Corruption?

No. The designation is part of the 2003 General Assembly resolution that adopted the Convention.

Can an observance page accuse a person of corruption?

Not without authoritative evidence. General awareness content should explain systems and verified cases rather than repeat unproven allegations.
