A short, defendable timeline
1945. The San Francisco conference drafts the Charter; it is signed 26 June 1945. The Charter enters into force on 24 October 1945 when the required ratifications are deposited — the UN’s legal birthday.
1947 and 1971. General Assembly resolution 168 (II) (31 October 1947) names United Nations Day for October 24. General Assembly resolution 2782 (XXVI) recommends that member states observe the day as a public holiday where appropriate. The United States does not treat it as a federal holiday; offices are not automatically closed. This page does not sermonize for or against the UN as the article’s thesis, claim U.S. federal-holiday status, or merge into National Food Day, Make a Difference Day, or World Food Day.
How to mark United Nations Day
- Read the Charter preamble (short, public text) so the anniversary has a primary source.

- Support a school Model UN or flag display if your community runs one.
- Follow HQ or mission event notes from official UN channels for the day’s public programs.
- Do not mix this page with National Food Day or World Food Day — different questions, even when calendars collide.
