In 1978, "Women's History Day" was celebrated in Sonoma County, Califonia. Championed by Gerda Lerner and the National Women's History Alliance, it began to be recognized as a national week in 1980 and then a month (1987) in the United States, spreading internationally after that.
Women's History Month highlights the contribution of women to events in history and society. In the United States, United Kingdom, and Australia, it is celebrated during March corresponding with International Women's Day on March 8th. In Canada, they celebrate during October corresponding with the celebration of Persons Day which takes place on October 18th.
