    International Plastic Free Day is a call to action and brings attention to the plastic we use every day. On May 25th, commit to using no single-use plastic for one day (including bottles, take-out food containers, utensils, bags and wrappers.)


    Over 380 million tons of plastic is produced every year. Half of all plastic produced is single-use – meaning it’s thrown away after just one use. Since only 9% of all plastic gets recycled, most of it ends up littering our communities, filling our landfills, and polluting our oceans.

    International Plastic Free Day creates awareness of just how much plastic we use every day, and how we can use less of it. Consider all the ways single-use plastic is used in our daily lives:

    • Beverage bottles
    • Cleaning products in plastic jugs
    • To-go containers
    • Food packaging
    • Cups, straws, lids
    • Storage bags
    • Product packaging

    Participation is simple: Say “No” to single-use plastics for one day. Don’t buy it, refuse it, don’t use it. The day also encourages learning how to swap sustainable products for single-use plastics. For example, swap:

    • Single-use straws with reusable bamboo straws.
    • Reusable tumbler for drinking both hot and cold beverages.
    • Reusable cloth bags for shopping.
    • Silicone bags for sandwiches and snacks.
    • Compostable garbage bags.


    Before May 25th, take the plastic-free challenge and commit to using no single-use plastics all day long. Every time you do, one less piece of plastic will be added to the environment. During International Plastic Free Day you can also:

    • Start a conversation about single-use plastic and its impact on the Earth.
    • Learn how plastic waste impacts our environment.
    • Discover one permanent change you can make to create less plastic waste.
    • Visit Free the Ocean for more ways to reduce plastic waste.

    When you participate, be sure to use #InternationalPlasticFeeDay and share on social media to help raise awareness.


    Plastic Free Free the OceanFree the Ocean founded International Plastic Free Day to raise awareness surrounding one of the most pressing issues involving our environment. The day is a call to action and brings attention to the plastic we use day-to-day.

    The Registrar at National Day Calendar proclaimed International Plastic Free Day to be observed annually on May 25th.



    Every year on May 25th, World Thyroid Day highlights this important gland in the body that causes widespread disease across the globe. The day also educates the public on the role of the thyroid in their overall health.


    The thyroid is a small gland located at the base of the neck. This butterfly-shaped gland produces two hormones: triiodothyronine (T3) and thyroxine (T4). Although the thyroid is a tiny gland, it plays a huge role in one’s health.

    The primary function of the thyroid is to control the body’s metabolism. Most people associate metabolism with how well you burn calories. But metabolism also affects body temperature and heart rate. If you have a problem with your thyroid, it affects your metabolic rate.

    Thyroid Conditions

    Thyroid conditions will either produce too little T3 and T4 or too much. When the thyroid doesn’t produce enough of these hormones, it’s called hypothyroidism. This condition usually happens when there is inflammation of the thyroid or there is an iodine deficiency. Iodine is the mineral that is used to make thyroid hormones. An autoimmune condition called Hashimoto’s can also cause hypothyroidism. Untreated hypothyroidism can cause brain fog, hair loss, gallstones, constipation, slow metabolism, bloating, heartburn, high blood pressure, and dry skin.

    Another condition associated with the thyroid is hyperthyroidism. This condition happens when the thyroid produces too much T3 and T4 and usually occurs with overactive nodules in the thyroid or too much iodine. A condition called Grave’s disease can also cause hyperthyroidism. This condition is a result of an overactive thyroid gland. Untreated hyperthyroidism can cause unintentional weight loss, rapid heartbeat, increased appetite, tremors, sweating, fatigue, and sleep issues.

    Anyone who suspects they have a thyroid issue, especially those with a family history of them, should see their doctor. There are many treatment options available for both hypothyroidism and hyperthyroidism.


    Many health organizations, clinics, and physicians hold educational seminars and presentations on this day. They encourage the public to learn more about thyroid conditions, along with their causes and treatment options. To participate:

    • Learn more about the symptoms of thyroid conditions.
    • If you suspect you have thyroid problems, schedule an appointment with your doctor.
    • Ask family members whether they have been diagnosed with a thyroid condition.
    • Donate to an organization that focuses on thyroid education and research.

    Share this important medical day on social media with #WorldThyroidDay.


    In 2007, members of Thyroid Federation International created World Thyroid Day. May 25th was chosen as it is the date in 1965 that the European Thyroid Association (ETA) was formed. The ETA was the first to celebrate World Thyroid Day. In 2010, the American Thyroid Association (ATA) declared their support of the day. Currently, the Latin-American Thyroid Society (LATS), the Asia and Oceania Thyroid Association (AOTA), the Chinese Society of Endocrinology (CSE), and the Chinese Society of Nuclear Medicine (CSNM) support the campaign as well.

  • TOWEL DAY – May 25


    Observed annually by fans of Douglas Adams, Towel Day commemorates the work of the author most known for his series The Hitchhiker’s Guide to the Galaxy.


    First and foremost, it’s important to note for those who are unfamiliar with Douglas Adams, according to The Hitchhiker’s Guide to the Galaxy, “A towel is about the most massively useful thing an interstellar hitchhiker can have.”

    And that’s mighty important. Even we mere Earthly hitchhikers require towels for many immensely useful purposes. We dry our furry pets and roll towels neatly into coordinated rows. On long trips, they ease the kinks in our necks. Even our tiny humans use them to dry off after taking a swim. Though, perhaps not very effectively. It can also offer shade on a sunny day.

    We’ve found that towels in small forms are effective for sport, too. Golfers and bowlers use them. Add a small towel to a footballer’s hip and call it a flag or wave a white one in a battle to surrender.

    In an emergency, a towel can stop bleeding or can carry the wounded. It also can cool a fever. Wrap it around you on a cool day. Wash a car or wipe up the oil. A really large towel might suffice for a toga party. However, in reality, it probably wouldn’t.

    The list of options goes on both here on Earth and beyond in every galaxy. The important lesson of the day is, don’t leave home without your towel.


    Pack your towel to celebrate the day. And when you do, be sure to share all the ways to use your towel. Join the conversation using #TowelDay on social media.

    For more tips and reading pleasure, check out these 7 Essential Ways to Use Towels.


    Towel Day was created in 2001 by Douglas Adams’ fans as a tribute to the author two weeks after his death on May 11th of that year.



    On May 25th each year, wine lovers everywhere pour a glass of their favorite wine to celebrate National Wine Day.  Whether it is Red or White, the sound of glassing “clinking” will be heard around the world today.


    Made from fermented grapes or other fruits, wine is an alcoholic beverage. During the fermentation processes, yeast consumes the sugars in the grapes converting it into alcohol.  Different grapes produce different wines.  Winemakers will combine different wines to create more complex flavors.  Wines made from fruit or honey are often named according to the variety of fruit used.

    Red wine varietals produce deep ruby reds as well as subtle ambers and browns. Their beautiful colors hint at the coming change in the season. With that, we can look for delicious menu changes, too. Besides, what better way to enjoy a great bottle of wine than by pairing it with excellent company and food.

    Winemakers produce white wines from grapes with light yellow-green skins or light red skins. However, it’s not the color of the grapes that give the wine its color. It’s the tannins in the grape skins that color wine red and also the flavor. White wines are generally sweeter than red wines and are best served chilled. Most red wines are served at room temperature. However, a sweet red should also be chilled for the best flavor.


    Reminisce with family and friends over a glass of wine.  Enjoy wine with a favorite meal.  And just a little tip, in a couple of days we celebrate National Coq Au Vin Day which includes red wine as an ingredient. Pick up an extra bottle to prepare. Post photos using #NationalWineDay on social media.

    National Brown-Bag-It-Day on May 25th each year recognizes the benefits of packing your lunch for work or school.


    Taking your lunch to work or school is an effective way to save money and to ensure you and your family are eating healthy. Some benefits to brown-bagging-it include:

    • Money savings – For every meal you make at home, you can save several dollars a day. This is especially true if you are normally prone to eating out, ordering in from restaurants or eating out of vending machines at work.
    • Better health choices – Will power and peer pressure don’t go well together. And when time is in short supply, we continue our poor decision making patterns. At home, we can plan our meals, and our choices are limited to the items we place in our fridge and cupboards. With practice, those items will be healthy ones, too.
    • Portion Control – Even though we try to control our portions while eating out, we know the serving size just keep getting bigger and bigger. When we brown-bag-it, we maintain that control.
    • Better for the environment – Paper bags are 100% biodegradable, reusable, and recyclable. When we re-use the same containers and recycle, we have more control over what is wasted. We also choose where our food is sourced.
    • Sturdier – Many paper bags can withstand more pressure or weight than plastic bags.
    • Paper bags present less of a suffocation risk to young children or animals.

    Unfortunately, paper bags also have a few not so great benefits:

    • Paper bags are not waterproof.
    • They are more expensive than plastic bags.
    • Take up more storage space and are often heavier.

    Paper Bag Terms

    Most common paper bag terms you may (or may not) care to know:

    • Paper basis weight: The thickness of the paper to construct a bag determines the basis weight increase. When the amount of paper increases, the basis weight increases. Paper bags with a basis weight of 30-49 lbs. is standard duty, and 50 lbs. or more mark heavy duty.
    • Gusset: The folded part at the bottom of the paper bag that expands when opening.
    • Flat Bottom Paper Bags: The most common type of paper bag.
    • Pinch Bottom Paper Bags: Have an attached bottom that is sealed across, mostly used for candy and greeting cards.

    Celebrate Brown-Bag-It Day on any of these other holidays on National Day Calendar:


    • Pack up your lunch in a brown paper bag.
    • Pick your favorite foods and enjoy a homemade lunch.
    • Make a puppet.

    On May 25 during National Tap Dance Day, we pay tribute to one of America’s original dancing art forms.   


    Tap dance is a percussive dance dating back to the early 1800s, with a combination of primarily influences of African and Irish heritage.

    Incorporating complex rhythmic step combinations, tap dance performers often expressed enormous amounts of character through sound and body movement. From clogging to buck and wing styles, soft-shoe to the sand step, and a little bit of jazz, tap dancing evolved from a stiff Irish jig to the bodily Cakewalk and vocal Ring-shout.

    Famous Tap Dancers

    • Bill “Bojangles” Robinson
    • Fred Astaire
    • Gregory Hines
    • Ginger Rogers

    Each of these performers added their own flair to a dance style that continues to influence film, music and stage.

    Another dance similar to tap dance is called soft-shoe. While still rhythmic, the sound is muffled since tap shoes are not necessary to perform the steps. Many of the dance steps in tap transfer to soft-shoe making the two very compatible.

    The popular Shim Sham of the vaudeville era became a line dance in the 1980s.

    HOW TO OBSERVE #NationalTapDanceDay

    Get your toes tapping and share your favorite tap dance experiences. There are so many ways to celebrate your appreciation of this entertaining art form.

    • Give a shoutout to your favorite tap dancer.

      • Tap Roots: The Early History of Tap Dancing by Mark A. Knowles
      • The Souls of Your Feet: A Tap Dance Guide for Rhythm Explorers by Acia Gray

    Let us know how you celebrate by using #NationalTapDanceDay to post on social media.


    On February 7, 1989, Congress reviewed a request for National Tap Dance Day. Carol Vaughn, Nicola Daval and Linda Christensen, all tap dancers and enthusiasts, brainstormed the idea for legislation while Christensen attended George Washington University. The bill came to fruition when President George H.W. Busch signed it into law on November 8, 1989. The law created a one-time official observance on May 25, 1989, the anniversary of Bill “Bojangles” Robinson, a significant contributor to tap dance born in 1878. The observance has continued to be celebrated each year on May 25th.

    Update, May 2022 – National Day Calendar was recently approached by one follower (Jamie S.) who wrote, “Hello. I was just reading about National Tap Dance Day and believe your history may be incorrect. I believe the first National Tap Dance Day came from a relative of mine. His name is Bill Robinson, not related to Mr. Bojangles, and I have documentation. I have a letter dated 2/17/1989 from a member of Congress approving his request for this National day. Please email me and I can forward the documentation. I believe he was the first to request the day and the people in your notations may have asked that it be recognized annually going forward.”

    From our correspondence with Jamie S., here is a PDF copy of the letter sent to Bill Robinson from Congress.

    Jamie tells us to this relative (Bill) is their cousin, who has since passed away, but Bill’s mother would love to know this National Day has honor and meaning to their family.




    National Missing Children’s Day on May 25th each year shines a spotlight on child safety. The day also honors the dedicated professionals who work tirelessly protecting children around the country.


    Most children who go missing do come home. Whether they’ve wandered off or there was a misunderstanding, many find their way back to their family.

    According to the Polly Klaas Foundation, 99.8 percent of children reported missing come home. Of those who are abducted, 9 percent are kidnapped by a family member. Only a small fraction are stranger abductions. However, the fact remains, if it happens to one child, that’s one child too many.

    Protecting Your Children

    While today’s observance honors those who’ve gone above and beyond to protect children, it’s also a good opportunity to offer resources to keep your children safe every day. It’s important to:

    • Maintain custody documents.
    • Keep recent photos of children handy.
    • Keep a copy of fingerprints.
    • Make sure medical and dental records up to date.
    • Monitor online activity.
    • Set some rules about who your child hangs out with.
    • Keep track of where your child is going.
    • Get to know parents of friends.
    • Complete background checks on caregivers and check references.
    • Never leave young children unattended in strollers and car seats.
    • Whenever possible, don’t dress children in clothing with their names on it.
    • Teach your child their address and phone number as young as possible.
    • Get to know your child’s friends.
    • Schedule events and gatherings in public places with your child and their friends and invite their parents, too.



        In 1983, President Ronald Reagan proclaimed National Missing Children’s Day recognizing the hundreds of thousands of children who went missing each year. Just a few short years before, six-year-old Etan Patz disappeared from his New York City home on his way from the bus to school on May 25, 1979. The observance commemorated the date of Etan’s disappearance. In addition, it also honored missing children everywhere. During the time of his disappearance, cases of missing children rarely gained national media attention. However, Etan’s case quickly received much coverage. Etan’s father, who was a professional photographer, distributed black-and-white photographs of his son to find him. As a result, a massive search, along with media attention brought public attention on the problem of child abductions. It also brought awareness to the lack of plans to address child abductions.

        Additional Information

        As much as we hate to think about it, there are some things you should do if you or someone you know has a missing child. In the first 24 hours:

        • Report the child missing immediately to a law enforcement agency.
        • Have authorities to have your child listed in the National Crime Information Center (NCIC) Missing Persons File. There is no waiting period for entry into NCIC for children under age 18.
        • Request authorities to issue a BOLO (Be On The Look Out).
        • If your child was abducted from your home, refrain from disrupting anything. Authorities normally collect evidence and moving, cleaning, throwing things way might hinder an investigation.
        • Get the name and phone number of the investigator working on the missing child case. Remember to keep this information nearby and readily available.
        • Provide as much detail about the facts related to the disappearance of your child, including what they were wearing.
        • Making a list of friends, family, teachers, and anyone else who might have any important information about your child, where they might have been or where they might go.
        • Tell authorities about work you may have had done or other people who were present at your home in the past year. Every detail helps.
        • Make copies of the most updated photo of your child, both in color and black and white. Make sure every law enforcement agency, missing children organizations, media and social media have copies.
        • Call 800-THE-LOST (800-843-5678) to ask for help with photo distribution.
        • Gather phone numbers for any nonprofit organization that might be able to help find the missing child.
        • With the help of authorities, organize a search party for your child, including the use of tracking vehicles, software, electronics and dogs.
        • Keep a detailed list of incoming and outgoing calls at or in your home with the time, person calling or making a calling and how long they were on the phone.
        • Find a support system to maintain your strength. Utilize any family or friends as much as possible.
        • Eat and rest. It may be hard, but taking care of yourself during this time is important.
