The United States celebrates 11 permanent legal public holidays, if you include the quadrennial celebration of Inauguration Day.

None of these holidays was created to celebrate women’s achievements.

Public holidays are literally etched in Americans’ psyche, appearing on published calendars everywhere. They allow 2.1 million federal employees and several million others whose offices follow the federal calendar, to spend time with their loved ones and, one hopes, take a moment to think about the reasons for that reprieve.

Federal public holidays also project our values to foreign allies, letting them know those causes most important to us. The United States holds itself out as a beacon of equality and democracy. If the rest of the world is to believe this, the U.S. must practice what it preaches.

But perhaps most simply, women have earned a federal holiday. Women have contributed to the national defense effort during every major war, helped expand our economy and advanced our nation’s literary and artistic heritage. Their contributions have been doubly commendable because they have made these strides while fighting to secure equal rights under the law and equal stature in the eyes of their male peers.

All Americans, regardless of gender, should recognize, support and cherish that shared history.

Congress could embrace International Women’s Day on March 8 as a general day of celebrating advances in women’s rights. It’s now a recognized holiday by the United Nations and more than 20 other countries, though not by the one from which the idea sprang: ours.

The Socialist Party of America started National Women’s Day in 1909, after thousands of women marched for better working conditions and higher wages in New York City; it was the model for the international version, created in 1910.

We could elevate to national stature Equal Pay Day, which aims to educate people on the persistence of the gender wage gap.

Or we could elevate Women’s Equality Day (Aug. 26) and celebrate the enactment of the 19th Amendment to the U.S. Constitution in 1919, which gave women the right to vote 143 years after Thomas Jefferson first wrote, with careful meaning, “All men are created equal.”

We could remember the birthdays of key leaders in the women’s suffrage movement, such as Anthony (Feb. 15), Lucretia Mott (Jan. 3), Elizabeth Cady Stanton (Nov. 12) or Ida B. Wells (July 16).

Congress’ failure to recognize women’s achievements is a relic of an unequal past. Congress should act today, buoyed by the groundswell of support for the women’s movement, the MeToo era, and the growing number of women serving in all branches of government.

As our first female vice president has said, as inspiration for young women and girls everywhere, “You’re going to walk into many rooms in your life and career where you may be the only one who looks like you or who has had the experiences you’ve had. But you remember that when you are in those rooms, you are not alone. We are all in that room with you, applauding you on.”

Congress, it’s time for you to use your voice. Show these women, girls and everyone who values America as a society of equals one more first: a federal public holiday celebrating a woman.
