Women's History Month is an annual observance to highlight the contributions of women to events in history and contemporary society. Celebrated during March in the United States, the United Kingdom, and Australia, corresponding with International Women's Day on March 8th, it began as a weeklong observation in Sonoma County, California in 1978. The celebration was subsequently championed by the National Women's History Alliance to be recognized as a national week (1980) and then month (1987) in the United States.
