Where the World Gathers to Celebrate Every Day


World Reef Awareness Day - June 1


World Reef Awareness Day on June 1st is a call to action for consumers, businesses, and organizations to reflect on the delicate ecosystem of our ocean’s coral reefs. The day brings together the general public, influencers and opinion leaders to create active change through education and engagement.

Coral reefs are living communities of colonial organism made of individual polyps that excrete a bone-like skeleton. This skeleton forms large rock-like structures that are homes for thousands of organisms.

The health of a reef tells us a lot about the health of an ocean. Many fish and ocean animals rely on the protection of the healthy, living reef for spawning season. The reef provides more than protection; it also supplies a rich, thriving food chain. From plankton and algae to the largest sea creatures, the reef ecosystem is a significant life support system.

The benefits of a healthy reef ecosystem go far beyond the ocean:

  • essential to the plant and fish-life
  • contribute to a lively fishing industry
  • protect beaches and coastlines from erosion
  • acts as the oceans filter
  • provide life-saving medicines and
  • possibly the one animal on the planet capable of consuming plastic

In recent years, our most productive reefs have been in decline due to coral bleaching. For example, the Great Barrier Reef decreased by 40 percent. It’s even worse along the Florida Keys and Caribbean, where decline is between 85 to 99 percent! According to Dr. Craig Downs, Executive Director of Haereticus Environmental Lab, about 90 percent of the reefs in the Caribbean have disappeared since 1980.

What causes coral reefs to die off?

  • Rising sea temperatures
  • Industrial pollution, plastic pollution, sewage
  • Chemical sunscreens and
  • Unmanaged, high-density tourism all threaten coral reefs.

One easy step we can take to protect these precious resources is by wearing non-nano zinc oxide sunscreen

According to Dr. Craig Downs,”When ingredients are uncoated and nano-size (less than 100 nanometers in diameter), they can enter the cells of invertebrates and fish and cause tissue damage, stressing all these marine organisms. Your best bet is to go for non-nano zinc oxide larger than 150 nanometers. At that point, the acute toxicity drops off, and the impact to ecosystems is mitigated”


On World Reef Day, educate yourself and spread awareness about how we can make simple choices today to save our reefs for tomorrow.

National Nail Polish Day - June 1


When the sandals come out, and the beaches heat up, it’s time for pedicures and manicures.  On June 1, National Nail Polish Day provides us with every shade under the sun to get us primed for summer!

From the French manicure to elaborate nail art, nail polish has come a long way since the bees’ wax and gum Arabic used by the Chinese around 3,000 B.C. National Nail Polish Day celebrates these durable lacquers and gels that last longer and provide variety.

No longer the status symbol it once was, nail color now changes with the seasons, our styles and our moods. There is a shade or hue for every occasion. Vibrant reds, turquoise and plum make summer nails shine during beach parties and weekend barbecues. The understated style of pale pinks and beiges or a subtle moss help us look workweek chic. For those elegant evenings or when we want to make a statement, nail polish adds gold, silver and sparkle to even the most economic wardrobe.

Mayor Keith Summey of North Charleston, South Carolina proclaimed June 1 as Say Something Nice Day in 2006 in recognition of the communication efforts of specialist Dr. Mitch Carnell founder of the day.  Carnell is also the author of Say Something Nice: Be a Lifter at Work. The South Baptist Convention and the Charleston-Atlantic Presbytery joined with Carnell to establish the day.

NATIONAL BUBBLY DAY - First Saturday in June


Pour a glass of sparkling sunshine to celebrate National Bubbly Day every first Saturday in June!

Bubbly, or sparkling wine, reflects the excitement associated with memorable events. Effervescent bubbles combine with the appealing flavors and aromas ranging from citrus, apple and pear to toasted fruit, spices and nuts. Whether paired with a full meal or light appetizers, these wines satisfy the requirement for an unforgettable celebration.

Different areas of the world create their own special brand of bubbly according to strict methods and select grapes which produce a sparkling wine unique to each region.

Produced in the rolling hills of Spain, Cava fills a glass with bright citrus and fruit notes. Protected in Spain, this bubbly must meet stringent requirements to earn the name Cava. Using only the “Traditional Method” which requires a second fermentation in the bottle.

While many people refer to bubbly as Champagne, to earn the name the wine must be made in the Champagne region of France with certain kinds of grapes and specific method. When celebrating with Champagne, enjoy the crisp flavors of apple or a nutty, sweet finish.

Another sparkle on the bubbly scene takes us to Italy and Prosecco. Made primarily from the Glera grape, Prosecco celebrates refreshing floral and fruit notes.


Pop the cork on a bottle of bubbly and celebrate by sharing a toast among friends! Use #NationalBubblyDay to share on social media.


Freixenet Cava, known for its iconic black bottle, founded National Bubbly Day to celebrate the wine that makes celebrations extraordinary and worthy of the word! Since 1861 and for five generations, the Ferrer family continues to bring quality bubbly to your celebrations where ever you are in the world.

The Registrar at National Day Calendar declared National Bubbly Day to be celebrated annually in 2017.


National Trails Day First Saturday in June


National Trails Day on the first Saturday in June recognizes all the incredible benefits federal, state and local trails provide for recreation and exposure nature. Events held throughout the United States help promote awareness of the wide variety of services the trails systems offer. National Trails Day encourages people to discover their local trials, become active concerning trail issues and share their excitement for the outdoors.

While hiking may be the first activity to come to mind, trails offer so much more!  Trails provide access to waterways for canoeing and paddle trips.  Birders find excellent opportunities for birdwatching and those seeking to test their abilities to observe and study geolocation enjoy geocaching. Others learn land navigation or use the trails for biking. Each of the pursuits creates an opportunity to spend time outdoors and generate an excellent cardiovascular workout.

National Trails Day is also an opportunity to thank the many volunteers, land agencies, trail developers,  park employees, rangers for their help in developing and maintaining the trails.


Visit your local trails. When possible, take a friend and try something new. Try a new trail, a new activity or introduce someone new to an activity you are skilled to pass on the experience to. Why keep it to yourself? Also, if you pack it in, pack it out. Show your appreciation to those who make the trail system possible.  Use #NationalTrailsDay to post on social media.


The American Hiking Society sponsors National Trails Day. For more information, go to National Trails Day.

National Go Barefoot Day June 1


National Go Barefoot Day is observed on June 1.  This day is an opportunity to kick off your shoes and run barefoot through the cool grass! More importantly, it is a day to help support a charity that provides millions of underprivileged children all around the world with shoes


Now is a good time to clean out your closets and donate a pair or two of gently used shoes to a charitable organization in your area or see the following for information:    Soles4Souls organization. Use #GoBarefootDay to post on social media.


National Go Barefoot Day was created by the people at Soles4Souls.  The holiday got its start after the Tsunami disaster in 2004 to support those affected by the event.  However, donations have continued to come in and over 19 millions of pairs of shoes have been donated worldwide since 2005.



National Olive Day is observed annually on June 1.  The olive, one of the world’s oldest fruits, is part of a traditional meze/tapas culinary experience that brings families and friends around the table to share time together rather than in a kitchen. The olive branch is a symbol of peace, hope, love and friendship and celebrating National Olive Day is a fun way to acknowledge the joy this little fruit provides.

Olives are used in many ways. We find them in cocktails and loaves of bread. We eat them whole as snacks, use them as toppings, include them on relish trays and even use them as a garnish for many foods. They are one of the most versatile foods we eat.


Take photos of your favorite way to eat olives and post them on social media using #nationaloliveday.


National Olive Day was submitted by Divina and proclaimed by the Registrar of National Day Calendar in July 2015.



Each year on June 1, National Heimlich Maneuver Day is observed. Using abdominal thrusts to force air from the lungs to expel an object on which someone is choking is called the Heimlich Maneuver.  Dr. Henry J. Heimlich created this life-saving procedure in 1974.  The Heimlich Maneuver is also referred to as “Abdominal Thrusts”.

Certified instructors teach the Heimlich Procedure, and these courses are available across the country. Today would be a good day to research the available training in your area.  According to the American Red Cross “choking causes over 3,000 deaths per year.” Having the proper training and knowledge may help to save someone’s life.

National Prairie Day - First Saturday in June


In North America, the prairies are at the heart of the continent. On the first Saturday of June, we recognize one of the richest ecosystems on the face of the earth with National Prairie Day.

A wide swath of central North America is comprised of flat grassland running from the Canadian provinces of Alberta, Manitoba and Saskatchewan down to Texas. Prairies are home to a wide variety of wildlife including prairie dogs, prairie chickens, buffalo, bison, elk, deer, rabbits, hawks, and foxes. Diverse native prairie plantings offer year-round food, shelter and nesting grounds for habitat.

What took thousands of years to form approximately 170 million acres has been reduced in the last 150 years to 1 percent of habitat.  Where once a vast and un-numbered variety of species thrived, the fertile soil now produces bumper crops of wheat, sorghum, flax, rye and oats.

The result is the loss of complex established ecosystems that once supported precious native birds, pollinators, insects and other native wildlife—habitat loss contributing to extinctions. What remains is teeming with diverse flora and fauna species, many endangered of becoming extinct, with some still yet to be discovered and identified. Original tracts of undisturbed prairie serve as living ecological and native American cultural research stations. These models of precious ecosystems with genetic resources continue to be studied, their ecological worth and economic benefits yet to be realized.

National Prairie Day is an opportunity to educate the public about preservation, conservation, and restoration opportunities as well as the history, wildlife and habitats of the prairie.   To understand the prairie is to look beyond what often initially appears simple, to learn about each form of life that thrives within it, to comprehend complex systems we can learn from, to ensure our future.  The natural beauty of prairies can be breathtaking.  Today’s “amber waves of grain” were created from the fertile soil of these oceans of grasslands that were once tall enough to hide a man on horseback. Prairies inspired the paintings of Harvey Dunn in South Dakota, poetry from Walt Whitman, and books from authors such as Laura Ingalls Wilder in Missouri.

Measurable Interrelated Benefits of Prairie Include:

Water Quality and Quantity Protection:
▪ prairie can absorb up to seven inches of rain without runoff
▪ prairie plants are adapted to drought, like having drought insurance
▪ watershed protection
▪ increase water infiltration and water yield, increase water supply by reducing erosion and reservoir sedimentation
▪ increase water quality due to the lack of fertilizer, pesticide, and herbicide use
▪ stormwater management prairie acts as a sponge that curbs soil erosion and flooding

Soil Quality and Quantity Protection:
▪ prairie soil microbes can reduce the amount of synthetic chemicals used in agriculture
▪ root systems of native prairie grasses firmly hold  soil in place to prevent soil run-off
▪ one acre of prairie can store well over one ton of carbon per acre per year
▪ native prairie plants with roots up to 15 feet deep act as a sponge, absorbing up to seven inches of rain without flooding

Birds, Native Pollinators, and Wildlife Protection:
▪ native bees are found to be 40 times more efficient pollinators than honey bees
▪ pollinator services for adjacent farms provided by native pollinators
▪ migratory waterfowl, shorebirds, waterbirds and songbirds
▪ animals adapted to wide open spaces with few trees

Energy Independence via Biofuels:
▪ prairie biomass can be harvested for renewable energy, creating natural gas

North American Cultural and Natural Heritage Conservation:
▪ primitive skills education
▪ Native American history
▪ homesteading

Plant Biodiversity Protection:
▪ management by grazing fire disturbance
▪ prairie plantings can be considered a form of drought insurance as they are adapted to drought, grazing, and fire
▪ forbs (native wildflowers) are of particular importance as food sources for native insects and wildlife
▪ endangered plant species have yet to be studied for their medicinal potential
▪ natural seed stores and propagation of endangered species


Learn about prairies by participating in a Prairie BioBlitz, visiting public prairies, supporting local, state, and national organizations that are committed to prairie education, conservation, and restoration.  At home, you can create your own prairie garden see how it changes through the seasons.

National Black Bear Day - First Saturday in June


On the first Saturday in June, National Black Bear Day recognizes the most commonly found bear in North America.

Also known as the American black bear, its scientific name is Ursus americanus. Despite their name, black bears can even come shades of cinnamon, blue/black, blue/grey and in rare instances, white. Found in 40 U.S. states and every Canadian province, the black bear’s enormous range is only beaten by one other four-legged mammal, the whitetail deer.

According to North Carolina Black Bear Biologist, Colleen Olfenbuttel, coastal North Carolina has the largest black bears on the planet. The current world record and the previous world record came from North Carolina. She also points out the northeastern part of the state also has the world’s highest black bear densities. In North Carolina black bears have access to high protein crops and enjoy mild winters – which is why they are so many bears and grow to be so enormous there. 

When a black bear stands on its hind legs, it has the most human-like qualities. They have a prey instead of a predator mentality, so they aren’t interested in eating you or your pets. Because they are omnivores, bears eat plants and animals. They forage for berries, roots, and insects, but will also eat small mammals, fish, and carrion. If a bear has been fed human food, it will also help himself to your picnic leftovers or camping supplies. This is where they have earned a bad reputation, but that’s why we shouldn’t feed the bears!


Learn more about the American black bear. It’s likely you live within driving distance of a preserve where black bears can be observed in the wild. Respect their habitat, follow the park’s rules, and you’ll get to view one of North America’s most extraordinary animals. Use #NationalBlackBearDay to share on social media.

NC Black Bear Festival LogoHISTORY

NC Black Bear Festival founded National Black Bear Day the first Saturday in June to celebrate America’s black bear while educating people about this magnificent mammal and dispelling many of the myths.

The Registrar at National Day Calendar proclaimed National Black Bear Day to be observed annually beginning in 2018.
