  • NATIONAL METRIC DAY – October 10


    On 10/10, National Metric Day recognizes the metric system, its history, and its benefits.


    The metric uses decimals as a method of measuring mass, distance, and volume. Though Simon Stevin, a Flemish mathematician, first suggested such a system in his 1586 publication De Thiende (The Tenth), centuries passed before the metric system became an accepted form of measurement.

    The metric system uses the following base units:

    • Meter – measures length
    • Kilogram – measures mass
    • Liter – measures volume

    These units are broken down by the power of 10 and the terms used for smaller and larger units carry across the base units. For example, a kilo is equal to the factor of 1000 and deci is equal to the factor of 0.1. A kilometer, kilogram, and kiloliter all mean translate to be 1000 of each base unit while a decimeter, decigram, and deciliter all translate to 0.1 of the base unit. This standardization makes for easy conversions. 

    Another metric unit of measure is Celsius. Also known as centigrade, this unit measures temperature. The boiling and freezing points of water are 100 degrees apart. While Fahrenheit marks the freezing point of water at -32°F, Celsius marks it at 0°C.

    U.S. Weights and Measures

    In the United States, the metric system became the preferred system for weights and measures in trade in 1988. However, the metric system still competes with the Imperial system of measurements. Distances are measured by miles, not kilometers. Recipes measure volume and weight by cups and ounces. Football measures distance by the yard. And yet, our doctors and mechanics rely on the metric system. We also purchase bottles of soda and water by liter measurements. Other occupations that predominantly use the metric system include:

    • Manufacturing
    • Pharmacy
    • Transportation
    • Energy
    • Healthcare
    • Technology
    • Restaurants

    On the 10th day of the 10th month, learn about this most accurate system of measurement.


    Celebrate the metric system by using it all day long. Test your skill and become accustomed to using metric units. Try these ways to celebrate:

    • Measure your speed and driving distance in kilometers.
    • Convert recipes or use recipes using the metric system.
    • Measure the temperature using Celsius.
    • Order beverages using the metric system.
    • Give measurements using centimeters.
    • Teach a metric unit on October 10.
    • Compare the Imperial System to the Metric System. What do you find?

    While you’re measuring up, share how you use the metric system by using #NationalMetricDay on social media.


    In 1977, the National Council of Teachers of Mathematics declared the week of May 9-13 as National Metric Week. Then in 1983, the council moved the observance to the week of October 10th to drive home the usefulness of the metric system. National Metric Day takes place on October 10th of that week.




    Public parks and green spaces are a community’s backyard. They offer nearby residents a place to play, connect, and reap the benefits of the outdoors. That’s why National Walk to a Park Day on October 10th encourages us to walk to our local parks. Feel the wind on your face. Take in the fall weather. Visit with neighbors. Play with your children. And appreciate all the benefits green spaces offer communities.


    Parks are an essential part of improving public health. They provide a place to play, exercise, and commune with nature. They support equitable and thriving communities. And they protect communities from the impacts of the climate. Yet, 100 million people, including 28 million kids, do not have access to a quality park within a 10-minute walk from home.

    National Walk to a Park Day is not only a celebration of green spaces but is a call to action for cities to ensure everyone across the U.S. has access to a quality park within a 10-minute walk of their home.

    As part of this national day, walk to your local park, encourage your community to support more public parks and green spaces, too.


    On National Walk to a Park Day, you’ll find many ways to celebrate. The first step is to step out of your home! Invite family, friends, and neighbors to join you. Add events to make your day at the park fun and memorable:

    • Walk your favorite route to your local park.
    • Bring sporting equipment – frisbees, balls, gloves.
    • Pack a picnic lunch.
    • Host a community event.
    • Bring a book or art materials.

    And don’t forget, public parks include playgrounds, beaches, trails, and some schoolyards. Capture your celebration in pictures and video and share them on social media, too. Tag them with #WalkToAParkDay and @10MinWalk and join the conversation!


    The Trust for Public Land launched the 10-Minute Walk Campaign on 10/10/2017, a movement that calls on mayors to ensure that everyone in US cities has access to a quality park within a 10-minute walk of their home. By 2021, the Campaign generated nearly 300 pledges from mayors across the country to increase park access for its residents. That same year, The Trust for Public Land founded National Walk to a Park Day on October 10th to further the campaign and focus on the importance green spaces play in our lives.

    The 10-Minute Walk Campaign accelerates the creation of parks that drive equitable, healthy, and thriving communities by calling on mayors to ensure that everyone in cities in the U.S. has access to a quality park within a 10-minute walk of their home.

    The Registrar at National Day Calendar proclaimed the first National Walk to A Park Day in 2021 to be celebrated on October 10th annually.




    Annually, World Mental Health Day on October 10th raises awareness and mobilizes efforts to support mental health.


    Mental health is a hot topic. This is good news. It means the stigma for mental health issues is slowly going away. Mental health issues are finally getting the attention they deserve. Healthcare workers and individuals feel they can discuss mental health more openly. However, that doesn’t mean there isn’t still work to do, however.

    As a whole, we often misunderstand mental health because it is hard to define. Additionally, mental health includes several areas. These areas involve one’s social, emotional, and psychological well-being. Mental health affects thoughts, feelings, and actions. When we have positive mental health, we handle stress better, our productivity remains stable, and we realize our full potential.

    When one has poor mental health, they are more likely to suffer from a mental health disorder. These disorders include the following diagnoses:

    • Depression
    • Generalized Anxiety Disorder (GAD)
    • Panic disorder
    • Phobias
    • Social Anxiety Disorder (SAD)
    • Obsessive-compulsive Disorder (OCD)
    • Post-traumatic Stress Disorder (PTSD)

    Of these mental health disorders, most people experience anxiety disorders. Statistics show that about 4% of the world’s population has a form of anxiety disorder. In the United States, the percentage increases to just over 18% of the population.

    Some people are at a higher risk of getting a mental health disorder. These include those with high-stress levels, those who have experienced trauma, and those who have few healthy relationships. However, family history plays a role in higher risk factors, too.

    Thanks to increased awareness and increased funding for research, there are effective treatment options for most mental health disorders. Conventional treatment methods include medication, psychotherapy, and hospital and residential programs.


    While not everyone faces a life with mental health issues, mental health impacts all of us. That’s why discussing mental health with your loved ones is a vital part of this observance.

    The World Federation for Mental Health organizes World Mental Health Day. Each year, organizations host a variety of events all around the world to increase awareness about mental health issues. Events include educational seminars, free mental health screenings, walk-a-thons, marathons, conferences, mass media promotions, and public service announcements.

    If you know someone who struggles with a mental health disorder, World Mental Health Day is a great way to reach out to them. While many people don’t feel comfortable talking to others about their diagnosis, knowing they have someone to reach out to makes a real difference. You can also donate to an organization that advocates for mental health. A few include the National Alliance on Mental Health (NAMI) and the Brain and Behavior Research Foundation. If you think you might have a mental health disorder or are at a high risk of getting one, schedule an appointment with your doctor.

    You can also discover more about the advancement of mental healthcare.

    National Cake Decorating Day on October 10th recognizes the creative artist who elevates cake design to another level. 


    Many professional cake decorators started their careers as hobbyists. It allows them to express themselves in an edible form. We make or purchase decorated cakes for many of life’s events, from baptisms and birthdays to weddings and anniversaries. Decorated cakes help carry out the theme of any party or event.

    Did you know cake decorators use at least six different types of icings? Depending on the kind of cake, they may use more than one type. Some help keep the layers together like glue. Others form designs better. And still, other types of icings or frosting add details.

    6 Types of Icing or Frosting
    • Butter Cream – This soft and very spreadable icing is tasty and preferred by bakers. It’s made with sugar and either lard, butter, or margarine.
    • Cream Cheese Frosting – By combining Butter Cream frosting and cream cheese, this rich and soft frosting pairs well with cupcakes and red velvet cake.
    • Fondant – Made with gelatin, glycerine, shortening, and other ingredients, this sculptable and moldable frosting builds a variety of designs on cakes.
    • Meringue – Egg whites, cold water, and granulated sugar beaten to a frothy consistency create a beautifully light and airy frosting. The final product may be served chilled or cooked to a crisp. This frosting often will be found on top of tarts or pies.
    • Royal Icing – A paste-like frosting, Royal Icing dries to a hard shell. Made from egg whites, icing sugar, and lime juice, this icing readily accepts colors.

    We ooh and awe at a beautifully presented meal or dessert. Cake decorators take the challenge and offer us works of Van Gogh, Monet, Frida Kahlo, Frank Lloyd Wright, and Julia Morgan in pastry form. Not only do we celebrate with dark chocolate ganache, but our eyes can’t imagine the feats before us. At times, cake artists also create sugar art, too. They delight us with their flavors and inspiring designs. 


    Decorate a cake. Thank your favorite cake, decorator. Give them a shout out and let them know you appreciate their hard work and dedication. Share your favorite designs or your memories of past cakes that impressed you. What would you like to see in cake design? If you’re a cake decorator, share with us your most impressive decoration.

    National Angel Food Cake Day on October 10th celebrates the delicious, light, and fluffy cake that many home cooks serve with fruit or glazes. 


    Originating in the United States and first becoming popular in the late 19th century, angel food cake was so named because of its airy lightness.  It was said to be the “food of the angels.”

    Making angel food cake requires whipping egg whites until they are stiff. Cream of tartar stabilizes the egg whites.  Additional ingredients are then folded into the egg white mixture.

    When is National Cake Day?

    The cake is then usually baked in an ungreased tube pan, leaving a hole in the middle of the cake. The center tube allows the cake batter to rise higher than other pans, causing the batter to clings to all sides of the pan.  After baking, the pan is inverted while cooling to prevent the cake from falling in on itself.

    Usually, rather than frosting, angel food cakes are topped with a glaze or a sweet fruit sauce and a swirl of whipped cream. Angel food cake also makes beautiful and amazing trifles. The airy layers absorb the flavors of fruit, caramel, liqueurs, and chocolate well. Another dessert that angel food gives an elegant look to is the parfait. 


    Bake up an angel food cake to share. Invite friends to taste with you. If you don’t have a recipe, try one of these. There are so many different varieties, it’s hard to choose!
