    On June 21st, World Hydrography Day highlights the importance of surveying and charting bodies of water. The day also encourages the general public to learn more about the science of hydrographs.

    It’s a known fact that 71 percent of the earth is covered with water. While most of the earth’s water is found in the oceans, it is also found in lakes, rivers, swamps, glaciers, and aquifers. It even exists in the air in the form of water vapor. Water is important for a number of reasons. Without water, humans and animals could not survive. We also use water for irrigating crops, keeping things clean, and providing recreational opportunities.

    Water also plays a key role in transportation. To navigate the earth’s waterways, scientists find out specific information. This information allows ships and other vessels to navigate the waters safely and efficiently. This falls under the science of hydrography. The information these scientists look for include:

    • Water depth
    • Shape of the seafloor and coastline
    • Location of possible obstructions
    • Physical features of water bodies

    Scientists use all this information to update nautical charts. These charts cover 95,000 miles of shoreline. Additionally, the charts cover 3.6 million square nautical miles of waters in the U.S. alone. Besides transportation and navigation, hydrography also helps in other areas. These areas include seafloor construction, anchoring, understanding fish habitats, and laying pipelines and cables.

    HOW TO OBSERVE #WorldHydrographyDay

    Every year the International Hydrographic Organization (IHO) hosts a variety of activities that focus on the annual theme. These activities include workshops, educational seminars, and conferences. To participate:

    • Learn more about hydrography and the importance of this science.
    • Find some nautical chart posters on the internet.
    • Do some educational activities with your kids, such as the build a boat challenge or making a compass.
    • Watch a documentary about water, such as Liquid Assets: The Story of Our Water Infrastructure or Watermark.

    Share this day on social media with #WorldHydrographyDay.


    The IHO created World Hydrography Day in 2005. That same year, the United Nations General Assembly adopted a resolution that recognized the establishment of this day. The date of June 21st coincides with the anniversary of the founding of the IHO in 1921 under the name International Hydrographic Bureau. The name changed to the IHO in 1970.

    Past themes for this day have included:

    2021: One hundred years of international cooperation in hydrography.
    2020: Hydrography enabling autonomous technologies.
    2019: Hydrographic information driving marine knowledge.
    2018: Bathymetry – the foundation for sustainable seas, oceans, and waterways.
    2017: Mapping our seas, oceans, and waterways – more important than ever.




    Capitalizing on the bountiful fruits and vegetables available this time of year, National Smoothie Day on June 21st celebrates the refreshing beverage brought to you by the blender.

    Using fresh ingredients, whole grains and punches of flavor, smoothies transform our fruits and veggies into a delightfully cool drink. Some smoothies incorporate herbs and spices, punching up the flavor level. The base ingredients include milk, yogurt, juice, and a blend of fresh and frozen fruits and vegetables in a variety of combinations.

    You may turn a little green when you consider adding vegetables to your smoothie, but don’t knock it until you’ve tried it. Both fruit and vegetable smoothies can pack in the nutrients, but be careful, the calories can also add up. Making smart choices will help keep your smoothies on the healthier side:

    • Limit your boosters – Ingredients like nut butters, seeds, grains and protein powders increase the fat and calories. While these ingredients add flavor and even nutrients, include them in small portions. You can also limit them to 1-2 per smoothie.
    • Control portion size – Just like our regular meals, smoothies can become oversized. Monitor the portion size for your main ingredients so that when your smoothie is complete, the calories and fat add up to a balanced serving. For example, one cup of berries, half a cup of yogurt and a tablespoon of a nut butter shouldn’t put you over.
    • Avoid juices – Prepared juices add calories. If you need a little more sweetness, consider adding a calorie-free sweetener or limiting the juice to just a splash.
    • Add veggies – Spinach, beets, kale and zucchini are just a few of the veggies that add nutrients and fiber without adding a lot of calories. And these veggies don’t add any offputting flavors.
    • Add a little spice – Cinnamon, ginger, nutmeg, and turmeric add flavor without adding calories. They also provide us with other benefits as well. Cinnamon, for example, may help lower blood sugar and blood pressure.

    Smoothies make a terrific meal substitute, too. When you’re craving something sweet or need an energy boost, a smoothie can be the answer.

    HOW TO OBSERVE #NationalSmoothieDay

    Visit your favorite smoothie bar and order your favorite combination. Share your recipes and invite someone to join you. Tell us what your favorite ingredients are, your tips and tricks, too. May we also suggest:

    • Try something new. Swap out one ingredient for another. You might find the best combination ever.
    • Give a shout-out to your favorite smoothie bar. They will appreciate it!
    • Share a photo of your beautiful smoothie!
    • Pick up a smoothie recipe book.

    However you celebrate, be sure to use #NationalSmoothieDay to share on social media.


    National Day Calendar continues researching the origins of this summer holiday.




    Every year on June 21st during the summer solstice, World Peace and Prayer Day encourages people of all faiths and all nations to pray for the planet. It’s also a day to learn more about Mother Earth and to inspire youth to care for the environment.

    Many people and cultures call our planet Mother Earth. They do so because the earth is considered the source of all its living beings. Mother Earth also focuses on the nurturing aspects of nature. Many people on the planet feel it is their duty to care for it. This includes Native Americans. They feel it is their duty, traditionally and culturally, to care for Mother Earth. Some even say that Native elders hold the key to living in balance on this planet.

    Native Americans are especially concerned about the earth’s water. They believe that everyone in the world was born from water. They also believe that water is medicine. For these reasons, they are concerned about the rivers drying up. They also lament the amount of plastic and other debris in our rivers, lakes, streams, and oceans that are killing wildlife. Many Native Americans believe that prayer can reverse these situations.

    HOW TO OBSERVE #PeaceAndPrayerDay

    On this day, Native Americans and other cultures gather at sacred sites around the world to pray. Besides Native American cultural sites, these sacred sites include churches, mosques, synagogues, temples, and other places of prayer. Artists, educators, civic leaders, and anyone else concerned about the environment are invited to participate. Besides prayer vigils, the event includes special speakers, showing of documentaries, sharing of stories, and fire and water ceremonies.


    In 1996, Chief Arvol Looking Horse began conducting the annual World Peace and Prayer Day during the summer solstice. According to cultures around the globe, the summer solstice is considered a powerful time to pray. Chief Looking Horse was born on the Cheyenne River Reservation in South Dakota. He is the Spiritual Leader of the Great Sioux Nation. He felt the need to create this day following the birth of a female white buffalo in 1994. The white buffalo’s name was Miracle and signified a time of changes on the earth as well as healing for the Nations.




    Every year on June 21st, the International Day of Yoga raises awareness about the benefits of this mind and body practice. It’s also a day to encourage people around the world to engage in Yoga.

    The word yoga means to unite or to join. This symbolizes the union of body and consciousness, and the philosophy originated in India about 5,000 years ago. One of the original goals of yoga was spiritual growth. Another goal was mastery over the physical and mental body. Today, two billion people around the world do yoga, some a form of exercise, and others to relieve stress. They have discovered all of yoga’s health benefits and that attributes to its growing popularity.

    Some of these health benefits include:

    • Improves flexibility
    • Builds muscle strength
    • Prevents cartilage and joint breakdown
    • Increases blood flow
    • Lowers blood pressure
    • Regulates adrenal glands
    • Improves balance
    • Prevents some digestive problems
    • Eases pain

    For those who want to give yoga a try, they should consider the different types of yoga. For example, Vinyasa yoga focuses on different postures and is the most athletic of all yoga styles. During Yin yoga, participants practice in seated postures and hold positions for longer periods of time. For a more meditative yoga, Anusara yoga focuses on the mind-body-heart connection.

    There is even prenatal yoga, which is geared toward moms to be.Expectant moms practice prenatal yoga because it concentrates on pelvic floor exercises and breathing. One more modern type of yoga is called goat yoga. And yes, it’s practiced in the presence of goats.

    Each type of yoga incorporates different poses and postures. Each of the poses has spiritual significance. Some of the most popular poses include Anjali mudra (the posture for prayer), mountain, tree, cobra, happy baby, downward-facing dog, and Savasana.

    HOW TO OBSERVE #InternationalDayOfYoga

    The celebration encourages yoga practitioners and studios around the world to hold family-friendly yoga classes. And many do! They host them in a variety of indoor and outdoor locations. Some of these yoga events schedule vendors, food trucks, and workshops, too.

    To participate in this day:

    • Attend a yoga event in your community.
    • Learn about the different types of yoga.
    • Buy a new yoga mat or some new yoga pants.
    • Try a new style of yoga you’ve never done before.
    • Watch a movie that features yoga and meditation, such as Kumare, Nobody’s Trip to Nowhere, or Living Yoga.

    To help spread awareness for this day, share your favorite yoga pose on social media with #InternationalDayOfYoga.


    In 2014, Prime Minister Narendra Modi of India proposed the draft resolution for International Day of Yoga. Recognizing the universal appeal of Yoga, 175 member states endorsed the resolution. On December 11, 2014, the UN proclaimed June 21st as International Day of Yoga. June 21st was chosen as it is the longest day of the year in the Northern Hemisphere. This date also holds special significance in countries across the globe.




    World Humanist Day is celebrated every year on June 21. It’s a way to spread information, and combat misinformation about humanism as a philosophical life stance and means to affect change in the world.

    The Encyclopedia Britannica says humanism originally was called “humanitas.” It meant the development of human virtue, in all its forms, to its fullest extent. The term thus implied qualities as such as “understanding, benevolence, compassion, mercy—but also much more assertive characteristics as fortitude, judgment, prudence, eloquence, and even love of honor. Consequently, the possessor of humanitas could not be merely a sedentary and isolated philosopher or man of letters but was of necessity a participant in active life.”


    Look for and attend a local lecture or discussion on or about June 21. Topics for discussion can range from the global, such as talks about the activities of the Humanists International, to the individual, such as open forums where people share their personal pathways to Humanism.

    In the late 1980s-early 1990s, the AHA and then the IHEU passed resolutions declaring the Summer Solstice to be World Humanist Day.

    • 2013, the first National Humanist Day was organized in The Netherlands.
    • June 21, which is the same day or close to the same day as the summer solstice. The solstice event has echoes of ancient communal gatherings, as well as reflecting humanity’s deepening scientific understanding of our world, and being an event that, by its nature, is shared globally at the same moment in the calendar.




    World Giraffe Day is an annual event initiated by Giraffe Conservation Federation to celebrate the longest-necked animal on the longest day of the year.

    It’s estimated there are 111,000 giraffes in the world. In some areas, traditionally regarded as prime giraffe habitat, numbers have dropped by 95%.

    Giraffe facts:

    • Giraffes are typically 14 to 20 feet tall.
    • Giraffes weigh between 1,600 and 3,000 pounds
    • A full-grown giraffe eats more than 100 lb of leaves and twigs a day.
    • Giraffes feed from the tops of trees, using their tongues and lips to pull off leaves.
    • Giraffe tongues are long, reaching around 20–21 in
    • Giraffes sleep less than two hours a day. In general, they sleep with their feet tucked under them and their head resting on their hindquarters, but they can also sleep for short periods standing up
    • Giraffe horns are not horns. They are ossicones.No one seems to know what they are for. The horns may help males intimidate one another during mating season, or they may be a sexually selected characteristic (that is, males with more impressive ossicones may be more attractive to females). It’s possible the ossicones may even help to dissipate heat in the blazing African sun.


    Adopt a giraffe at Giraffe Conservation Federation. Follow on social media with #WorldGiraffeDay to join the conversation.


    The first World Giraffe Day was organized by the Giraffe Conservation Federation in 2014.




    On June 21st, National Arizona Day recognizes the state that joined 48 states into a contiguous unit. Interestingly, Arizona became a state on Valentine’s Day in 1912.

    Arizona is home to the oldest continuously inhabited settlement in North America. Established around 1000 A.D., the village of Old Oraibi is located on the Hopi Indian Reservation in Navajo county.

    Known as the Grand Canyon State, Arizona brings the wilderness to you. The breathtaking views of the Colorado Plateau, which incidentally took over 70 million years to form into towering stone, are now one of nature’s grand centerpieces.

    Carved into limestone cliffs along Beaver Creek, a well-preserved dwelling towers above the scrubland below. Home to the Sinagua Indians around 1500 AD, the Aztecs mistakenly named this place Montezuma Castle.

    Like many of the Western states, Arizona Easterners came with the prospect of land, gold, and adventure. Cowtowns were born, and battle lines were drawn between those who wanted the territory and those who were already there.

    Find your way to the Saguaro National Park to see the mighty cacti of the west. These majestic plants of the desert can grow up to 50 feet tall. Under the right conditions, they can live to be over 150 years old.

    If you’re not buying the line “It’s not the heat, it’s the humidity,” and the soaring daytime summer temperatures of Arizona get to you, Lake Mead may be the cure. With hiking, watersports, camping, and beaches, there are plenty of ways to relax, have fun, and cool off. Plus this Arizona Bucket List Adventure Guide & Journal fits the need for any adventure you desire.

  • NATIONAL SEASHELL DAY – First Day of Summer


    On the first day of summer, National Seashell Day reminds us to put our toes in the sand and admire the beauty of seashells.


    Shellers get ready to shellebrate and start shelling! To those not in the know, shellers are beachcombers who collect seashells by scouring the beaches for the gems left behind by snails and mollusks. National Seashell Day is here to tell you all about it and make sure you check out your local beaches during the prime shelling season.

    For a sheller, the true tulip or lettered olive is almost more mesmerizing than the ocean sunset. Or maybe it’s the hunt for the rare or the unique specimen. These jewels of the sandy beaches, the king’s crown conch, the apple murex, or even a pear whelk dazzle beachcombers. Their names are as musical and colorful as your adventure will be, so grab your bucket and head out around sunrise or sunset. Seashells are waiting for you!

    Tips for Shellers:

    • Never collect live shells. When in doubt, always put them gently back in the water.
    • Check local ordinances. Only take a small number. Shells are part of the ecosystem helping to preserve and create the beaches we enjoy visiting.
    • The best time for shelling is one hour before and one hour after low tide.
    • Follow the high tide shell line where the largest waves stop.
    • Watch for full and new moons. They have a higher gravitation pull on the tide and reveal more seashells.
    • Storms churn up the ocean floor sending more shells to the surface and the shore for collection.


    Make your way to your favorite beach to collect your treasures or schedule a shoreside vacation to start your seashell collection. Share your seashell collections and beachcombing tips by using #NationalSeashellDay on social media.


    The Beaches of Ft. Myers & Sanibel founded National Seashell Day on the first day of summer in 2016 to celebrate seashells and the extraordinary shelling found in Southwest Florida.

    The Registrar at National Day Calendar proclaimed National Seashell Day to be observed annually in 2017.



    National Day of the Gong on June 21st honors the gong’s unique history among instruments of sound, creativity, and healing.


    Mighty and gentle, earthy, and celestial, this extraordinary instrument is a conduit of Creation. With an international cultural history, the gong offers sensory and multi-dimensional sounds. Thanks to artisans worldwide, gongs come in an array of sizes, designs, and origins. As an instrument, they are both beautiful in design and performance. While gongs originate in the East or Southeast Asia, they also have an ancient history in Rome.

    Stonehenge of Texas in Ingram

    Percussionists play these circular metal discs by striking them with a mallet. The tones or pitch vary depending on the size and shape of the gong. Other factors impact the tone as well. For example, gongs may be rimmed or rimless, shallow or deep. They may also be flat or bossed or knobbed in the center. The mallet also influences the resulting music and is used to play rhythms, creating melodies.

    While the gong is an ancient instrument, it has become a profound presence within diverse performances and ceremonies. It also offers modalities for the Mind-Body-Spirit. Traditional and contemporary artists bring the gong alive through imaginative and effective spectrums of expression.


    The celebration encourages us to enjoy, explore, create, and collaborate on this powerful day. Listen to the gong and its fascinating sounds, and vibrations, and work in the world! Other ways to explore on #DayOfTheGong include:

    • Discover the different styles of gongs and the sounds they make.
    • Attend a performance.
    • Learn to play the gong.
    • Find out how a gong is made.
    • Meditate or attend a spiritual session using a gong.

    Use #DayOfTheGong to share your experiences on social media.

    Thanks to social media and the smartphone, June 21st recognizes a form of self-portrait that couldn’t exist without them; It’s National Selfie Day! We are encouraged to take creative (appropriate) selfies and share them on social media.


    While the act of taking a selfie may predate social media, smartphones, and the word itself (which is now in the Oxford Dictionary), the popularity of taking these self-portraits keeps increasing. And the ability to take them gets easier all the time. Selfie sticks and multi-functional camera phones make it all too convenient to take these kinds of photographs as well as group selfies (aka groupies).

    Selfies have become so popular, the most common types of selfies are earning names for themselves. Most of them are about documenting a moment in time, though others merely capture a look. They are called “selfies” after all. They usually feature a single person and that’s the person taking the photo. However, not all of them are about the photographer. We’ve gathered a few of them worth checking out.

    Duck Face Selfie

    The subject pushes out their lips almost as if going for an exaggerated kiss but it turns into a duckbill instead. Hence, the duck face.

    Car Selfies

    Social media is full of channels with videocasts located from the seat of one’s car. They’re informative, helpful, political, and funny. So, it shouldn’t surprise us that car selfies are a thing, too.

    Bathroom Selfies

    Where do we look our best? Before the wind and stress of life hit us, we look our best in the bathroom.

    Pet Selfies

    Next to our life partners, who do we love the most? Our pets. We take selfies with our cats, dogs, lizards, parrots, and so many more pets.

    Bestie Selfie

    Our besties might tie with pets for our love. It depends on the person. Either way, we take lots of selfies with our besties. #BFF, right?

    Foodie Selfies

    Why do we take selfies with food? It may be that it’s so beautifully presented or it’s our first time trying an exotic food, and we want to document the event. No matter the reason, foodie selfies are a thing.

    Glamour Selfie

    Other than the bathroom selfie, sometimes we look really, really good. Good hair day. The makeup is pristine and you’re dressed to impress. While you didn’t get all dressed up to take a selfie (or did you?), for some of us, the opportunity may not come around again. It’s best to get some proof.

    Gym Selfie

    Speaking of looking our best, sometimes a gym selfie is necessary to show progress. It also gives our friends the opportunity to say, “Hey, I haven’t seen a gym selfie lately. Are you slacking?”

    Celebrity Selfie

    If you find yourself on the train, in a coffee shop, or just on the street and see your favorite musician, author, or television celebrity, you’re going to stop and ask for a selfie. These popular little selfies make the rounds.

    Travel Selfies

    The Eiffel Tower. The Grand Canyon or the Hollywood sign. Broadway lights. Selfies in front of these epic locations add to a traveler’s collection. They’re like postcards to yourself.

    Baby Selfies

    Whether they are with your children, grandchildren, or other people’s children, baby selfies usually make us look good. We can’t help but smile. We can strategically place them in front of our bad spots. And they just improve our overall character.

    Tattoo Selfie

    Getting some ink is a major decision. Taking a selfie either while you’re getting it or afterward is part of the process.


    Take selfies of you and with your friends and family. Post your favorite selfies from your travels or from group gatherings. Even if you’re not very good at taking selfies, we’ve got you covered with 7 Selfie-Taking Tips. Use #NationalSelfieDay to share on social media.


    In 2014, DJ Rick McNeely founded National Selfie Day.
