The second Monday of January each year recognizes National Clean Off Your Desk Day.

This day is an opportunity to begin your new year with a clean and organized workspace.  Whether your desk is in a private or shared office, cubicle, home or a make-shift desk on the counter, having your workspace uncluttered and organized will help you work more efficiently. A clean workspace improves productivity and inspires us, too. It often gives us a sense of serenity.

HOW TO OBSERVE #CleanOffYourDeskDay

While there are those who say they know where everything is, we all know a clean start helps give us a new perspective.

Tips for Getting Organized
  • Remove everything from your desk. Yes, everything.
  • Clean the surface. As you replace items, clean them with the appropriate cleaning supply. Usually, a damp cloth is sufficient, but other electrical items need specific care.
  • Get out the shredder and the garbage can. Shred, file, scan documents, business cards, recipes, photos as needed.
  • Place all documents and photos in the appropriate locations.
  • Shred and toss outdated documents, non-working pens, junk mail.

Don’t forget to replace that old calendar hanging on the wall. While you’re at it, vacuum up those dust bunnies and sanitize your keyboard. Place a fresh box of tissues on your newly cleaned desktop. You’ll be ready for new clients in no time.  Use #CleanOffYourDeskDay to post on social media.


While researching the origin of this tidy day, National Day Calendar staff uncovered information leading to A.C. Viero of Clio, Michigan as the founder of this annual holiday. Now that we can see the top of our desk, we can clearly see there will be more paperwork in our future! 



National Milk Day on January 11th commemorates the day many think the first milk deliveries in glass bottles began in the United States. Alexander Campbell of the New York Dairy Company professed to the New York State Senate that his company was the first to make these deliveries in 1878. 

The United States and Australia export more milk and milk products than any other country. Those products include cheese, yogurt, ice cream, butter, cream, powdered milk, and much more. Throughout the world, more than 6 billion people consume milk and the products we make from it. One of the reasons is because milk provides nutrients such as calcium, potassium, vitamin B12, and vitamin A. 

Production History

During the Middle Ages, people called milk the virtuous white liquor because alcoholic beverages were more reliable than water. In 1863, French chemist and biologist Louis Pasteur made it possible for milk and other food and drinks to be stored for more extended periods. He developed a method of killing harmful bacteria that is now called pasteurization. 

In 1884, an American doctor, Hervey Thatcher of New York City, developed the first modern glass milk bottle. He called it the “Thatcher’s Common Sense Milk Jar.” He used a waxed paper disk to seal the milk in the glass bottle. Later, in 1932, plastic-coated paper milk cartons were introduced commercially as a consequence of their invention by Victor W. Farris. 

Modern industrial processes use milk to produce casein, whey protein, lactose, condensed milk, powdered milk, and many other food-additive and industrial products. 


The females of all mammal species can, by definition, produce milk. However, cow milk dominates commercial production. In 2011. FAO estimates cows produced 85% of all milk worldwide. Apart from cattle, many kinds of livestock contribute milk used by humans for dairy products. These animals include buffalo, goat, sheep, camel, donkey, horse, reindeer, and yak. Like cattle, their milk produces cream, butter, yogurt, kefir, ice cream, and cheese, too. 

HOW TO OBSERVE #NationalMilkDay

The ultimate way to celebrate is with a large glass of milk. However, a serving of anything made with milk would count, too! Does a milkshake sound good to you? We’ve gathered up some other ways to celebrate, too!

  • Make your own cheese
  • Add chocolate, strawberry, and malted flavorings to your milk. Then blindfold the kids and have a milk tasting!
  • Invite a friend for homemade hot chocolate
  • While drinking your milk, learn more about the nutrients in milk

In 1915, The International Association of Milk Inspectors submitted a request to Congress in October of 1915 for a resolution naming an observance of National Milk Day. Their request did not suggest a date for the observance. We have no record that the incoming Congress ever presented a resolution for National Milk Day, nor did incoming President Woodrow Wilson ever declare the day.

National Day Calendar continues the search for the creator of the day.

    National Human Trafficking Awareness Day on January 11th brings attention to a crime that leaves a lasting toll on human life, families, and communities around the world. 

    Beginning in 2010, by Presidential Proclamation, each January has been designated National Slavery and Human Trafficking Prevention Month.  Following the start of National Slavery and Human Trafficking Prevention Month, with the help of non-government organizations, National Human Trafficking Day began and is observed annually on January 11th.

    Human trafficking is considered a modern form of slavery. This illegal act involves the use of force, fraud, or coercion to obtain labor or sex. Traffickers use violence, manipulation, or false promises to lure their victims into trafficking situations. Trafficking victims usually experience physical and/or psychological abuse. They might also endure sexual abuse, food and sleep deprivation, threats to family members, and isolation from the outside world. Family members of the victim may also get threatened.

    The goal of the day is to bring greater awareness to the crime of sex trafficking. Each year, organizations around the globe provide support to communities, training to volunteers and educational events to increase awareness.

    HOW TO OBSERVE #HumanTraffickingAwarenessDay

    One way to get involved is through the 31:8 Project. The organization works to equip and challenge society to proactively address issues regarding human trafficking. Human Trafficking takes away the voice of its victims and Project 31:8 aims to speak for them – Proverbs 31:8 – speak up for those who cannot speak for themselves.

    Their work is on track to reach over 25,000 people in 2019 through presentations, training, webinars, and community projects. Visit their website at www.318project.org to learn more.

    • Write or call your legislators and let them know your support policy that combats human trafficking.
    • Support events that improve awareness in your community, schools, and neighborhoods.
    • If you suspect someone is a victim of human trafficking, contact the National Human Tracking Hotline at 1-888-373-7888. You can also contact local law enforcement by calling 911.
    • Empower young people to make the decision to leave an unsafe or suspicious environment.

    The United States Senate designated January 11th as National Human Trafficking Awareness Day in 2007.



    On National Step in a Puddle and Splash Your Friends Day, particular criteria must be present to celebrate. On January 11th, unless the ideal conditions prevail, some areas of the country may have to create them. So, can we really? Well, yes, the name of the day says you can!  Life is short….let’s have fun! And good luck. 

    If you are feeling somewhat mischievous (in a nice kind of way), join in on the celebration that all kids will love and all the young-at-heart adults will love just the same. Put on your boots, raincoats, slickers and grab some rubber duckies, too. Skip along the way. Splashing in puddles can be a terrific way to relieve stress. There’s no right or wrong way to splashing or stepping in a puddle. We’re going to get wet and probably a little dirty no matter how you do it. So splash away. 

    Now, if you live in a more frozen region of the country, we encourage you to find alternative ways to celebrate. We know you’ll be creative and safe. 

    HOW TO OBSERVE #StepInAPuddleAndSplashYourFriendsDay

    On National Step in A Puddle and Splash Your Friends Day, invite your besties to join you for a fun-filled time reliving those days when you didn’t worry about getting your feet wet. Dance and splash in the puddles! Sing some splashing in puddle songs or check out this great video expressing the joy of splashing in puddles.

    While puddle diving, National Day Calendar continues researching the origins of this wet and wild day.

    In 2017, National Day Calendar® began celebrating each state in the order they entered the union starting the week of Independence Day and ending with Hawaii. We highlight a small part of each states’ history, foods and the people who make up the state. Many states have their own state celebrations, and National Day Calendar’s observances in no way replace them. There’s so much more to explore, we can’t help but celebrate our beautiful country even more!



    On January 11th, National Arkansas Day recognizes the Natural State and the 25th state to join the union.

    Populated by Osage, Caddo, Quapaw tribes when French and Spanish explorers arrived in the area, Arkansas teems with streams, lakes, and rivers.  Its eastern border is the Mississippi River. Little Rock may be its capital, but Arkansas is also known for big rocks and lots of rocks and minerals. It’s the Quartz Crystal Capital of the World, has the only diamond mine in the U.S., and the Magnet Cove region contains 102 varieties of minerals.

    Arkansas earns the name “Natural State” with over half the state is forested and more than 1 million acres in Ozark National Forest.  But that’s not all that contributes to the apt nickname.

    Hot Springs National Park became America’s first national preserve in what later became the National Park System. When Arkansas was still a territory, officials recognized the unique qualities of the hot springs and requested the area be set aside and protected. President Andrew Jackson signed legislation on April 20, 1832, designating four sections of land which included the hot springs and adjacent mountains “…reserved for the future disposal of the United States (which) shall not be entered, located, or appropriated, for any other purpose whatsoever.”

    What’s in a Name

    When Arkansas first became a state in 1836, how to pronounce the name of the 25th state was up for debate. Was it Arkan-saw or Ar-kansas? The issue was settled in 1881 when the State General Assembly passed Concurrent Resolution No.4. It stated the state’s name would be pronounced Arkan-saw and spelled Arkansas.

    Many who have called Arkansas home have left marks on our hearts and minds. From the legendary Johnny Cash and talented composers, Scott Joplin, and Roberta Martin, to authors Ernest Hemmingway and Maya Angelou and many more found a home at some time in Arkansas.

    Nestled along the Mississippi River, Arkansas swells with delta, Civil War era, the blues and jazz, and Western migration history.  The worst maritime disaster in United States history occurred on the Mississippi River just north of Marion, Arkansas. Greater than the Titanic disaster, the Sultana steamboat exploded on April 27, 1865, just weeks after the end of the Civil War and the assassination of President Lincoln. Over 1,800 souls perished.
