    Get geared up for International Legging Day every October 18th. Although it’s a year-round staple, when temps drop in the fall, it’s officially legging season!


    Once a necessity providing an added layer of warmth, the legging is now an iconic style combining comfort and fashion. Leggings truly set a trend in the 1950s and ‘60s as a standard wardrobe piece and workout essential.

    Over time, breathable materials, textures, designs, and prints ushered in the undeniable era of leggings. Now, modern-day leggings are feats of engineering designed to enhance your workout. While they continue to be a gym essential, legging styles are now so versatile that they’re widely acceptable to wear as pants. In a wide range of looks, comfortable leggings offer something for everyone.

    As the popularity of athleisure skyrockets, so too does the mass appeal of the legging. Clearly, this comfortable, curve-hugging style hasn’t just revolutionized what we wear to the gym—it’s revolutionized what we wear everywhere! The versatile legging has sparked a global revolution that encourages women to embrace comfort and stay active.


    Put your best legging forward! Proudly wear your favorite pair and go shopping for more. Consider this your chance to break the dress code—whether it’s at the office or that five-star restaurant you’re dining at tonight. After all, feeling comfortable is what the day’s really all about. Share your favorite looks and styles by using #LeggingDay on social media on October 18th.



    Fabletics founded International Legging Day in 2019 to celebrate the year-round style staple during the official legging season.

    The Registrar at National Day Calendar® proclaimed International Legging Day to be observed on October 18th, annually.

    October 18th Celebrated Birthdays

    Frederick August Otto Schwarz – 1836

    The German immigrant created magic long before Walt Disney ever did. In 1861, Schwarz and his brothers opened their first toy store in Baltimore Maryland. Schwarz would open a second store in New York City named Schwarz Brothers – Importers. Over the years, the store became a destination for millions of toy lovers around the world. Early in the 20th century, the store was renamed FAO Schwarz and is the oldest toy store in the United States. In 2012, Frederick Schwarz was elected to the Toy Industry Hall of Fame.

    Harry Yarnell -1875

    Prior to World War II, the naval officer proved the vulnerability of Pearl Harbor during the annual Grand Joint Army and Navy Exercises. He served more than 51 years with the U.S. Navy and retired from service in 1942 but returned to duty several times during World War II.

    Lina Radke – 1903

    In 1928, Radke raced for Germany and won the first Olympic 800 meter race for women. It was the first year the Olympics allowed women in athletic events. Held in Amsterdam, the race was considered controversial because popular and medical opinion believed women too frail for competition and athleticism. Following the race, reports of collapsing runners, runners dropping out of the race, blazed the headlines. However, despite photographic and film evidence proving none of the 9 runners dropped out of the race or collapsed, the news refused to report the actual headline – that Radke won and broke the world record. Tragically, the race would be removed from the Olympics and would not return until the 1960 Olympic Games in Rome.

    ​Isabel Briggs Myers – 1897

    Briggs Myers teamed up with her mother Katharine Cook Brigs to develop what became one of the most widely used personality inventories. The self-reporting questionnaire called Myers-Briggs type Indicator (MBTI) measures 16 personality types as well as other indicators and offers tools for understanding.

    Trixie Worsley – 1921

    Not only was Worsley the first Canadian woman to become a computer scientist, but she may have also been the world’s first woman to earn a doctorate in computer science.

    Chuck Berry – 1926

    The Grammy-winning and Rock and Roll Hall of Famer, Chuck Berry influenced generations of musicians and artists. With a slew of number one hits, Berry ushered in the era of Rock & Roll. His first hit song, “Maybellene,” was followed by “Roll Over Beethoven,” “Brown Eyed Handsome Man,” and “Johnny B. Goode,” along with several other popular songs in between. He continued to perform well into the 1990s.

    Mike Ditka – 1939

    The former professional football player led the Chicago Bears as head coach for 10 years. During his tenure, he led the Bears to a Super Bowl win in his third season. He continued to lead the Bears in winning seasons but they didn’t appear in the Super Bowl again under Ditka’s leadership.

    Zac Efron – 1987

    The singer and actor rose to popularity thanks the Disney hit High School Musical. He continues to earn Teen Choice and People’s Choice awards. In 2017 he played Phillip Carlyle in The Greatest Showman. His most recent production is a travel web series called Down to Earth with Zac Efron.



    On October 18 (1018), National Exascale Day celebrates the scientists and researchers who make breakthrough discoveries in medicine, materials sciences, energy and beyond with the help of some of the fastest supercomputers in the world.


    We like to say that National Exascale Day celebrates those who keep asking what if, why not, and what’s next — with the advanced technology to attain the answers.

    This era in technology will have a profound impact on nearly every aspect of our daily lives. It will impact everything from healthcare and manufacturing to understanding new energy sources and the origins of the universe. Exascale is defined as a quintillion computations per second. For perspective, if all 7.7 billion people on earth each completed one calculation per second, it would take over 4 years. An exascale computer can complete a quintillion computations in 1 second.

    So what, you may ask?

    The “so what” is that when science discovers and innovates in less time, it realizes good outcomes sooner. More people survive cancer. Populations deplete fewer natural resources from the earth. More people have healthy food on their tables. And so on.


    Celebrate the geeks, gurus, and geniuses who keep asking the big questions and are changing the world! To get you started, here are a few ideas:

    • Hug a scientist.
    • Encourage your teams to recognize the great work of a colleague, researcher or anyone who is using advanced computing to change the world.
    • Tell the world via your organization’s website, blog, and media channels how your org views the impacts of Exascale computing on the future.
    • Take a scientist or science teacher for lunch.
    • Celebrate with your teams – ice cream social, picnic lunch, or special recognition ceremony.
    • Keep science alive in your schools by sponsoring a science fair.

    Use #NationalExascaleDay to share on social media. Keep reading to learn even more!

    We’ve included a bit more information below for your curious-er types.

    Fun Factoids
    • Exascale computing means a computing system that can perform at least one exaflops ― or one quintillion (a billion billion) calculations per second.
    • It would take 40,000 years for one quintillion gallons of water to spill over Niagara Falls.
    • The Milky Way galaxy is 1 quintillion kilometers wide.
    • The human brain contains 100 billion neurons – to reach one quintillion would require 10,000 people!
    • Exascale computers will be roughly a million times more powerful than the average laptop we use every day.
    A Historical View into the Next Inflection Point

    The advent of the Internet allowed business and industry to collect data like never before. Fast forward, data growth continues to drive organizations of all sizes to data-intensive computing and digital transformation. In response, AI, analytics, IoT, simulations, and modeling workloads are all converging into one business-critical workflow – a workflow that must operate at an extreme scale and in real-time.

    So, data growth, converging workloads, and the imperative for digital transformation mean organizations are asking completely new questions. And they need new capabilities to answer those questions. Exascale computing completely rethinks how technology and people come together to answer today’s biggest questions ― and even bigger ones tomorrow.

    What Makes Now an Exascale Era™?

    Exascale is more than a speed milestone or a system size. Exascale is new workloads brought on by new questions intersecting with new compute capabilities to create a major technological shift.



    CRAY, a Hewlett Packard Enterprise company, founded National Exascale Day in 2019 to celebrate the people who keep asking, “what if, why not, and what’s next?” — with the advanced technology to attain the answers. The day also celebrates a new era of supercomputing that will enable breakthroughs in disciplines benefitting all of humankind.

  • BRA DAY USA – Third Wednesday in October



    BRA (Breast Reconstruction Awareness) Day USA is observed on the third Wednesday in October.


    Each breast cancer campaign brings a special focus on an area of concern. However, few shine a light on options after mastectomy or lumpectomy like BRA Day USA.  While reconstruction may not be for every woman, they should have access to the available options so they can make informed decisions.

    Deciding whether to reconstruct breasts after a mastectomy is a personal decision. For some, the decision is a difficult one. It is important that patients are provided with all the information and tools to make the best decision for them. Remember, they’ve lived with their body, their breasts all their life. For many women, they’ve shaped the clothes they’ve worn, fed their children, and been a part of their more intimate life.

    Women who chose to not have reconstruction performed also have choices. Prosthetic design and technology continually advance. Each woman should be provided with all their options. Her network should support her in every way through the journey and reassure her that whatever decision she makes is the right one for her.


    Recognize the day by supporting someone you love who’s facing a decision after a mastectomy. Offer support and listen. Help them formulate their questions for the doctor. What’s best for one person may not be the best option for another. Use #BRADayUSA to share on social media.


    Dr. Mitchell Brown, a Canadian plastic surgeon, started BRA Day in 2011.  The event expanded to the United States in 2012 as BRA Day USA.

    Breast Reconstruction FAQ

    Q. Where can I find more information about breast reconstruction surgery?
    A. The American Cancer Society provides detailed information regarding breast reconstruction surgery.

    Q. Where can I find more information about mastectomy?

    Annually, National No Beard Day on October 18th celebrates the cleanshaven among us. The smoother the face, the bigger the celebration!


    Whether you have had your beard for years or it is relatively new for you, this is the day to shave it off and go smooth. Perhaps your partner doesn’t like your beard, or you just haven’t shaved it off for years. No Beard Day is the day to see what you look like without it.

    Achieving a close, kissable shave is a lost art that faded with a generation that had the first color televisions installed. Consider investing in the tools your grandfather or possibly your great-grandfather used – either a safety razor or a straight razor will give you the closest shave along with a natural bristled shaving brush and shaving soap. More care and time may be required, but the results are well worth the effort.


    Shave and post before and after photos on social media using #NationalNoBeardDay.

    You can also explore beard styles in preparation for growing your beard out again. Check out these 7 Popular Beard Styles Throughout History.


    National Day Calendar® continues researching the origins of this fashionable holiday. However, next month is No Shave November and since we are halfway through October, indications suggest we start there.


  • MEDICAL ASSISTANTS RECOGNITION DAY – Wednesday of Third Full Week in October


    Medical Assistants Recognition Day is observed on Wednesday of the third business week in October. One of the fastest-growing careers in the nation, medical assistants make medical offices run more smoothly and are instrumental in overall quality patient care.  


    Medical assistants are health professionals who support the work of physicians and other health professionals, usually in a clinic setting. Their responsibilities can include both administrative and clinical duties.  Depending on the type and size of the facility, what state, certifications available and the laws affected by where they work, medical assistants can play a variety of roles.  

    When is Dental Assistant Recognition Week?

    On Medical Assistant’s Recognition Day, take time to thank these healthcare professionals for their dedication.


    Make sure your medical assistants know how much you appreciate their hard work. Host a luncheon in the office or treat them to their favorite coffee. Give out fun awards such as “Fastest on their Feet” or “Memory Better Than A Chart.” Or, take a more serious approach by offering updated training to advance their careers. 

    Use #MedicalAssistantsRecognitionDay to post on social media. Be sure to also give a great big shout out to all you know today in healthcare!

    National Chocolate Cupcake Day on October 18th annually celebrates the sweetness of small chocolate cakes. With a dollop of frosting, one sweet serving satisfies chocolate and cake lovers!


    Cupcakes have also been called:

    • Fairy Cakes
    • Patty Cakes
    • Cup Cakes (different from Cupcakes (one-word))

    Cupcakes can be traced back to 1796 when a recipe notation of “a cake to be baked in small cups” was written in American Cookery, by Amelia Simmons. The earliest known documentation of the term cupcake was in 1828 in Seventy-five Receipts for Pastry, Cakes, and Sweetmeats in Eliza Leslie’s Receipts cookbook.

    Bakers initially baked their cupcakes in heavy pottery cups. However, bakers today use a plethora of tools at their fingertips. Some still use individual ramekins, small coffee mugs, large teacups, or other small ovenproof pottery-type dishes for baking their cupcakes. Of course, the most common cupcake tool is the muffin or cupcake pan. This handy tool includes multiple cups in one device.

    Chocolate cupcakes come in a variety of flavors, too. Of course, there’s always the standard chocolate cupcake. But why stop there on a holiday?

    • Chocolate caramel cupcakes satisfy that extra cry for sweetness.
    • Peanut butter chocolate cupcakes are the snacker’s delight.
    • Get devilishly good cupcakes with Devil’s Food.
    • Cool things off a bit with chocolate mint recipes, too.
    • And you can’t forget chocolate orange cupcakes. Citrus brightens the flavor of any chocolate recipe.


    Celebrate by trying one of the following tempting recipes while watching an episode of the Food Network reality-based competition show, Cupcake Wars. Remember to invite friends or family over to share. That’s how we like to #CelebrateEveryDay!

    Cream Cheese Chocolate Cupcakes
    Chocolate Fudge Cupcakes with Peanut Butter Frosting
    Super Easy, Super Moist Chocolate Cupcakes

  • HAGFISH DAY – Third Wednesday in October


    On the third Wednesday in October, Hagfish Day brings awareness to the evolved but slimy hagfish. 


    Hagfish are considered to be the ugliest of species. The idea behind this observance is to encourage everyone to look beyond the exterior of the Hagfish and appreciate how highly evolved they are. Not unlike a book cover, the day points out the benefits of looking deeper into the subject.

    The hagfish offers many benefits to the ecosystem. Despite its unappealing exterior, it scavenges the ocean floor, cleaning up the debris of dead marine animals. The slime they produce protects them from predators. While it’s thinner than human hair, the slime is stronger than nylon. Researchers are seeking the potential commercial, medical and environmental uses of slime. The military also sees its potential. For example, Navy researchers developed a synthetic hagfish slime using E.coli bacteria. U.S. Biochemist Dr. Josh Kogot and materials engineer Dr. Ryan Kincer hope the strong synthetic slime can provide added protection for naval vessels. 

    In some cultures, this eel is even considered a delicacy. Though the meat is mild, it can have a bitter aftertaste. 


    Learn more about the hagfish and its benefits. Visit an aquarium near you or read up on this fascinating creature. Use #HagfishDay to post on social media. And, if you have images of some you have caught, why not show them to the world?


    WhaleTimes founded Hagfish Day in 2009 to ‘beauty of ugly’ and raise awareness of the importance of all animals – not just the pretty ones. 

    Hagfish FAQ

    Q. What do hagfish eat?
    A. These scavengers of the sea most often eat dead and dying animals on the ocean floor. Their process adds to the gross factor, too. Despite being jawless, they often burrow into a carcass and eat it from the inside out. However, they are also known to hunt.

    Q. How big do hagfish get?
    A. With 76 species of hagfish in the world, the smallest hagfish grows to about 18 cm and the largest to 127 cm.

    Q. Where do the hagfish live?
    A. Hagfish populate the cold waters of all the world’s oceans.
