Women's History Month started officially with a Congressional Resolution declaring the week of March 8 as National Women's History Week in 1981. This week was chosen in order to focus on International Women's Day which is March 8. In 1987, the National Women's History Project petitioned Congress to extend the week to the whole month of March.

Observances highlight the interconnection of women to each other, the historical contributions of women, and recognition of women workers. A major focus of the month is to educate schoolchildren by introducing them to the many vital contributions of women and to encourage them as future contributors. Activities usually focus on current issues facing women, especially as they relate to the workplace.

Activities at the Oak Ridge National Laboratory are planned and implemented by the ORNL Women's History Month Committee in cooperation with the Office of Workforce Diversity.
