Overview

International Women's Day is observed on 8 March as a global day focused on women's rights, equality, participation and achievements. Its history predates the United Nations and grew out of labour, suffrage and women's-rights movements in the early twentieth century.

The United Nations began celebrating 8 March as International Women's Day in 1975 during International Women's Year. The day therefore has both a movement history and a later UN institutional history, and those two layers should not be collapsed into a single “UN-created” origin story.

Why it matters

International Women's Day can be used to examine progress and remaining barriers in political participation, education, work, health, safety, economic opportunity and equal treatment. Responsible observance should focus on rights and agency rather than reducing the day to generic praise or commercial celebration.

Because women are not a single uniform group, useful activities should also consider how disability, race, ethnicity, age, migration, poverty and other circumstances can shape access to rights and opportunity.

History

UN Women records that International Women's Day was first commemorated on 19 March 1911 in Austria, Denmark, Germany and Switzerland after its establishment at the Socialist International meeting the previous year.

The modern 8 March date is linked to women's demonstrations in Russia in 1917. In 1975, during International Women's Year, the United Nations began celebrating International Women's Day on 8 March.

On 16 December 1977, the UN General Assembly adopted resolution A/RES/32/142, inviting States to proclaim a United Nations Day for Women's Rights and International Peace on a day chosen in accordance with national traditions. That resolution strengthened the UN institutional framework around the observance, but it did not itself require every State to use 8 March.

8 March The stored recurrence guidance is: 8 March.

Does International Women's Day fall on the same date every year?

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

Is International Women's Day an official public holiday?

The authority record verifies it within this scope: United Nations-recognized international observance. That recognition does not by itself make it a statutory public holiday; the site only makes public-holiday claims when the supporting authority record explicitly does so.

Who established or recognizes International Women's Day?

The reviewed provenance layer identifies International socialist women’s movement / Socialist International meeting (1910) as the proclaiming or establishing body. The proposer or originator is recorded separately as Socialist International meeting in Copenhagen (1910).

Is International Women's Day international or country-specific?

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

How is this page verified?

The factual layer is source-backed and keeps its date rule, scope, provenance and editorial guardrails attached to the authority record. This record was checked on 2026-09-05.

When is International Women's Day?

Did the United Nations create International Women's Day?

What did the 1977 UN General Assembly resolution do?

Resolution A/RES/32/142 invited States to proclaim a United Nations Day for Women's Rights and International Peace according to their historical and national traditions. It strengthened UN recognition of the women's-rights observance framework without fixing one mandatory date for every State.
