Women’s History Month is celebrated during the month of March. In 1987 after being petitioned by the National Women’s History Project, Congress passed Pub. L. 100-9 which designated the month of March 1987 as Women’s History Month. Between 1988 and 1994, Congress passed additional resolutions requesting and authorizing the President to proclaim March of each year as Women’s History Month.

Since 1995, presidents have issued a series of annual proclamations designating the month of March as Women’s History Month. These proclamations celebrate the contributions women have made to the United States and recognize the specific achievements women have made over the course of American history in a variety of fields.
