Women’s History Month is a celebration of women’s contributions to history, culture, and society and has been observed annually in the month of March in the United States since 1987.

We celebrate Women's History Month to reflect on the often-overlooked contributions of women to United States history. The actual celebration of Women’s History Month grew out of a weeklong celebration of women’s contributions in 1978. In 1980, President Jimmy Carter issued the first presidential proclamation declaring the week of March 8 as National Women’s History Week. 7 years later, the event expanded to the entire month of March.
