Why do we need Women Veterans Day? Women Veterans Day, also referred to as Women Veterans Recognition Day and Women Veterans Appreciation Day, is the anniversary of the day the Women’s Armed Services Integration Act (pub.L. 80–625, 62 Stat. 356) was signed into law by President Harry S. Truman on June 12, 1948. Prior to then, only women nurses could serve in the regular and reserve forces during peacetime.
