Presidential Proclamation 2017

The roots of National Women’s History Month go back to March 8, 1857, when women from various New York City factories staged a protest over working conditions. International Women’s Day was first observed in 1909, but it was not until 1981 that Congress established National Women’s History Week to be commemorated annually the second week of March. In 1987, Congress expanded the week to a month. Every year since, Congress has passed a resolution for Women’s History Month, and the president has issued a proclamation.
