When did March become Women’s History Month?

Origin of the observance

March as Women’s History Month began as a local celebration in Santa Rosa, California, in 1978, expanding from International Women’s Day (March 8). School districts organized a "Women’s History Week" to highlight women’s contributions often omitted in standard curricula. The idea that a single month should formally recognize women’s historical impact emerged from this grassroots effort, reflecting a broader social movement to correct historical omissions and include women’s experiences in public memory.

From week to month: national expansion

After initial local success, advocacy for a longer period gained momentum across school districts and community organizations. By the early 1980s, congressional activity and presidential involvement were critical in transforming a regional event into a national observance. Lawmakers and women’s organizations sought a formal mechanism to ensure consistent recognition, leading to legislative steps that would eventually establish the month-long observance.

Presidential proclamations

Presidential involvement began in 1980 when Jimmy Carter issued a proclamation declaring the week of March 8 as National Women’s History Week. Subsequent presidents continued the practice, issuing annual proclamations that emphasized education, reflection, and the recognition of women’s achievements. These proclamations provided a consistent, recurring acknowledgment at the highest executive level, reinforcing the legitimacy and permanence of the observance.

Legislative milestones

Congressional action was essential to change the designation from a week to a month. In 1987, Public Law 100-9 established March as Women’s History Month, codifying the observance in federal law. The law formalized expectations for ceremonies, activities, and programs across federal agencies, while encouraging schools and communities to expand their programming. This legislative milestone represented institutional commitment to ensuring that women’s history remained part of the national conversation year after year.

Why March was chosen

March was selected to align with International Women’s Day on March 8 and the existing traditions within the women’s movement that already highlighted women’s contributions during this time of year. The proximity to International Women’s Day provided a logical and symbolic anchor, connecting local, national, and global observances. March thus served as a familiar touchstone while also offering an extended period for reflection, education, and celebration.

Observance and impact

Today, Women’s History Month is marked by schools, cultural institutions, government agencies, and community groups across the United States. Activities include lectures, exhibitions, curricula, and events that explore women’s roles in history, science, politics, arts, and everyday life. The month serves both educational and commemorative purposes, aiming to correct historical imbalances and inspire future generations by highlighting women’s achievements, struggles, and ongoing influence on society.
