    National Vitamin C Day on April 4th each year shares all the ways vitamin C nurtures and benefits our health, inside and out!


    While Vitamin C is widely recognized for warding off colds, the vitamin is also clinically proven to be a powerhouse in other areas of health, too. For example, Vitamin C may reduce blood pressure and potentially lower the risk of heart disease. Those at risk of gout can lower that risk by increasing their intake of Vitamin C.

    Topically, Vitamin C keeps skin healthy by protecting it from oxidative damage caused by daily exposure to light, heat, and pollution. The popularity of topical vitamin C products has risen dramatically.

    With the right product, adding Vitamin C to your beauty regimen can brighten your skin, reduce inflammation, and promote healthy collagen production. Vitamin C brightens just about any health routine.

    SkinCeuticals founded National Vitamin C Day in 2019 to celebrate this research and the proven benefits of vitamin C.

    The research of Dr. Sheldon Pinnell, founding scientist of SkinCeuticals, established the parameters for effective vitamin C antioxidant delivery to the skin, allowing SkinCeuticals to pioneer the emergence of cosmeceuticals.

    The Registrar at National Day Calendar proclaimed the day to be observed on April 4th annually.

    April 4th Celebrated History

    The people of Argonia, Kansas, elected Susanna Salter as their mayor. Her name was placed on the ballot as a prank against the opposition, but it backfired. Salter was the first woman elected as mayor in the United States and had more than just a little understanding of politics. She was also a member of the Women’s Christian Temperance Union and set into practice her teetotaler ways. That same year, she also gave birth to a son.


    The nutritionist Charles Glen King isolates vitamin C while conducting a study at the University of Pittsburgh. Though Hungarian biochemist Szent-Gyorgyi earned a Nobel Prize in 1937 for isolating the vitamin first, many believe King deserves recognition for his work.


    The civil rights activist and clergyman, Dr. Martin Luther King, Jr. dies when assassin James Earl Ray murders him in Memphis, Tennessee. King has arrived to support other Southern Christian Leadership Conference leaders during a sanitation workers’ strike when Ray ended the nonviolent Civil Rights leader’s life.

  • SAAM DAY OF ACTION – First Tuesday in April


    Each year on the First Tuesday in April, Sexual Assault Awareness Month (SAAM) Day of Action provides a day to focus awareness on sexual violence prevention. Nationally recognized in the United States and observed annually as part of Sexual Assault Awareness Month (SAAM), SAAM Day of Action provides tools and resources throughout the campaign. 


    The day aims to stop sexual assault, harassment, and abuse before they happen through education. Teaching about consent and understanding boundaries is important, but requires a societal change, too. Currently, the stigma of sexual assault rests with the victims. Until that view changes, sexual assault will continue to go unpunished.

    Through social media campaigns, events and more, the day promotes valuable resources to help change the societal view. The day also provides ways to support victims throughout the month and beyond. 


    • Show your support by sharing social media posts on Instagram, Facebook, and Twitter.
    • Learn about consent and how it works.
    • Attend or register for an event.
    • Use #SAAMDayOfAction to post on social media.

    Each year on April 4th, National Chicken Cordon Bleu Day celebrates a blue ribbon dish that combines chicken, ham, and cheese.


    The French term Cordon Bleu translates to “Blue Ribbon.” This dish is a take on the popular Veal Cordon Bleu. It is a flattened chicken breast that is wrapped around ham (or sometimes prosciutto or Canadian bacon) and cheese such as Swiss or Gruyere. Toothpicks hold the chicken together before being dipped in an egg wash and breaded.

    The earliest recipe we were able to find was in a March 1964 printing of the Cincinnati Enquirer by the Cincinnati Gourmet Stanley Demos. Despite some misconceptions, it is an American dish. Demos mentions in his column that he got the idea to try chicken instead of veal “to be different.” It has been a popular dish since.


    • Make chicken cordon bleu or a variation on the theme. Several recipes offer lighter varieties, too.
    • Share your favorite recipe for this creative chicken dish.
    • We also found a recipe for you to try in your home kitchen.
    • Order chicken cordon bleu at your favorite restaurant.

    A. Yes. Though variations on the recipes create appetizers with similar ingredients.




    On April 4th each year, National School Librarian Day recognizes the professionals who keep the school library in working order. School librarians spend long hours keeping the library organized. They are also dedicated to helping our children find the resources they need to keep learning. School librarians are the people who create an environment where students can learn every day of the year. Their work is an impressive accomplishment.


    The school librarians provide guidance and expose our youth not only to texts, print media, and literature but to digital resources and technology, too. These resources also connect them to libraries around the world. A school librarian’s ability to manage scores of media and a school full of students with numerous projects and schedules astounds us.  


    • Remember the school librarian on this day. Take a little gift or a card and tell them “Thank You!”
    • We’ve created a postcard just for the occasion. Download and print it on cardstock. Make sure your printer settings are set to print on both sides of the paper. The cards are 5.5 x 4.25 inches. Then color and mail the postcard to your librarian and let them know how much you appreciate them.
    • Share your experiences as a school librarian.
    • Learn more about the history of libraries and those who work in them.
    • Use #SchoolLibrarianDay to post on social media.


    National Day Calendar continues to research the origins of this school holiday. However, librarians and school librarians have been celebrated for decades. School districts or individual schools often launched celebrations recognizing their librarians. These celebrations took place at different times throughout the school year. It wasn’t until more recent decades that the practice took place during Library Week or other reading-related celebrations.

    National Hug a Newsperson Day (formerly National Hug a Newsman Day) on April 4th encourages appreciation for the people reporting the news.  


    The Merriam-Webster dictionary tells us that the word “newsman” dates back to 1596. They have been working hard for many years to bring us the news from around the world.

    A few well-known newspersons include:

    • David Brinkley
    • Katie Couric
    • Walter Cronkite
    • Ann Curry
    • Lester Holt
    • Peter Jennings
    • Connie Chung

    Your local newsperson reports on the days’ events in your community. They keep you informed of important political news, businesses in your community, weather, traffic, crime, and education updates. When it comes to the national news, the local news reporters apply local perspectives. While events may happen thousands of miles away, a local newsperson knows it impacts their views still. 

    On the national and world scale, a newsperson may travel far and wide for the complete story. Some are attached to certain regions of the world, specializing in political, economic or health news. Wherever they report from, they bring the news into our homes, cars, businesses or where ever we may be. They keep us informed of the ever-changing world around us.


    • Hug a newsperson. (Ask for permission first.)
    • If you aren’t able to hug your newsperson, you can send them a virtual one.
    • You can also download our coloring page. When you’re finished coloring it, send it to your favorite newsperson to show them how much you appreciate them.
    • Or solve the word search puzzle we created for the day using common news words.

    National Walk Around Things Day on April 4th each year is a holiday open to interpretation. Very little information is available regarding this celebration, so we’ll give it our best to guide you through it.


    This day may be looked at both figuratively and literally. Literally, one would not walk through a puddle of water or mud; one would walk around it. One would not walk under a ladder or over broken glass, one would walk around both.

    Figuratively, one would “walk around” avoiding certain problems or potential problems. One would also “walk around” avoiding arguments, certain situations, or unwanted or uncomfortable conversations.

    Another possible intent of this day could very well be to walk around things such as a neighborhood, park, or shopping mall. While we’re walking around we might also walk around obstacles or structures we come across during our stroll. We might find a fountain or swingset to walk around in a park. At the mall, benches and planters interrupt our easy stride. Of course, at home, we have all sorts of things that we walk around willingly. Sometimes the reason we walk around these items is pure avoidance like laundry or clutter. We might also walk around a sleeping pet. 


    • Make a point to walk around things or subjects. No matter what you decide to walk around, make sure you do it properly:
      • Warm-up those muscles. 
      • Wear good shoes. 
      • Keep your head up and maintain good posture.
      • Swing your arms.
      • A brisk walk is about 20 minutes per mile. Walking around things might slow you down, though. 
    • Other ways to participate in National Walk Around Things Day might include:
      • Take photos of the things you walk around.
      • Count how many things you walk around. (That might become more tedious than walking around them.)
      • Leave things for others to walk around. For example, a mysterious obelisk in the middle of the living room.
    • Share your achievements using #WalkAroundThingsDay to post on social media.


    National Day Calendar continues to research the origin of this vague and yet possibly useful holiday. To make a point, we’ll walk around and see what else we can find out about the day. 

    Walk Around FAQ

    Q. Isn’t it easier to step over things?
    A. Not always. If it’s a large object or your legs don’t work well, going around the object is better.

    Q. Is this day about picking up after yourself?
    A. It might be. Maybe someone’s mother tired of them walking around the toys, clothes, and other things left around the house.

    Q. How many frequently asked questions could there be about walking around things?
    A. That’s a good question. How many do you think there are?
