International Women’s Day (IWD) is a global day celebrating the social, economic, cultural and political achievements of women.

It has been observed since the early 1900s.

The catalyst for it was a march that took place in 1908 with over 15,000 women campaigning for shorter hours, better pay, and voting rights.

The first National Woman’s Day was celebrated across the United States on February 28 1909.

The idea to make the day international came from Clara Zetkin, who suggested the idea at the International Conference of Working Women in Copenhagen in 1910.

International Women’s Day was agreed to be marked annually on March 8 and has remained the global date for the holiday ever since.
