Annually observed in March, Women's History Month originated as Women's Day on February 28, 1909. A gathering of Manhattan socialists and suffragists organized this event to commemorate the one-year anniversary of the garment strike led by the International Ladies' Garment Workers' Union. History contributor Sarah Pruitt notes that the meeting took place on a Sunday to ensure that participants wouldn't miss work.
