"In March 1980, President Jimmy Carter issued the first Presidential Proclamation declaring Women’s History Week to align with International Women’s Day (March 8th) which has been recognized across the world since March 1911. The following year, on August 4, 1981, the U.S. Congress established Women’s History Week as a federally recognized commemoration of the accomplishments, perspectives, and experiences of women in the United States with a Joint Resolution, Public Law 97-28. This week became a month-long celebration in 1987 when Congress passed Public Law 100-9 and then passed subsequent resolutions requesting that the U.S. President make an annual declaration. Since 1995, each U.S. President has declared March to be Women’s History Month." Source: Women's History in the United States. Edsitement.neh.gov.
