D-Day – June 6


June 6, 1944, is known most commonly by the term D-Day and refers to the landing of Allied forces on the beaches of Normandy, France. Troops staged one of the most pivotal attacks against Germany during World War II.

The codename Operation Overlord became known as the beginning of the end of World War II. Following the Battle of Normandy along a 50 mile stretch of beaches, including Utah and Omaha Beach, the attack became known as D-Day. While many explanations exist for the name, one reason may be due to the military countdown. The countdown designated the day and hour of the assault. D represented Day and H represented Hour in the military.

The battle liberated Northern France. Britain, the United States and Canada sent more than 160,000 Allied troops under the leadership of General Dwight Eisenhower. The troops manned more than 5,000 ships and 13,000 aircraft the day of the initial landing.

After nearly five years of war, D-Day represents a vital turn in the war. During World War II, much of the world faced tragedy and hardships. D-Day continues to be a significant point in the war.


On June 6th, World War II museums, memorials, and ceremonies honor the Allied forces who landed along the 50 mile stretch of beaches in 1944. Learn more about the Battle of Normandy by exploring World War II museums. You can read books about the Battle of Normandy or listen to a podcast such as:

The landing of troops on the beaches of Normandy on June 6, 1944, known around the world as D-Day, was given the name Operation Overlord. Leading up to the attack, plans of deception were carried out to mislead Germany.



National Gardening Exercise Day is observed each year on June 6th and encourages us to maximize the benefits we reap from gardening by adding some stretches and a few extra steps or squats.

Gardening on its own is therapeutic, builds muscles and burns calories. Some of the gardening activities that are excellent for working your muscles and for burning calories include weeding, digging, spading, planting, pruning, mowing, raking, and walking.

Many of us do not realize the amount of healthy exercise that we can get while working outside in the garden. It involves a lot of walking back and forth as well as bending up and down along with other things. Being out in the fresh air and sunshine are also an added benefit. Incorporating stretching into a gardening routine may help to prevent injury, much like it does for any athletic endeavor.  Adding those squats will contribute to building or maintaining muscle, and extra steps may make gardening more aerobic if it increases the heart rate. Gardening and exercise are excellent stress relievers, too!

HOW TO OBSERVE #GardeningExerciseDay

Pull those weeds, plant some seeds, and get your muscles moving! Your garden will look great, and you will feel fantastic, too!

Other suggestions to get the most exercise out of your gardening:

  • Start slowly. Just like any new workout program, small steps.
  • Use the right and left hands equally.  When raking or shoveling, switch hands every 5-10 minutes to give each side a good workout.
  • Make sure to breathe. Deep, cleansing breaths bring oxygen to those working muscles.
  • Lift with your legs! When lifting, bend your knees. Don’t lift with your back.
  • Drink plenty of water.
  • Enjoy your garden. Visit it often!

Gardening is a favorite hobby for several National Day Calendar staff. We want to share with you some of our favorite gardening items. Show us how you celebrate by using #GardeningExerciseDay on social media.

    Observed annually on the first Sunday in June, National Cancer Survivor’s Day sets aside time to “demonstrate that life after a cancer diagnosis can be a reality.”

    The day is a way for survivors to share their journey and offer hope and inspiration to those who have been newly diagnosed. Cancer survivors know the emotions and challenges associated with receiving a cancer diagnosis. They also know where the resources and support are for newly diagnosed cancer patients. The day encourages a celebration for survivors and their families. The day also offers a wellspring of support and outreach to cancer patients everywhere.

    While every cancer and treatment is different, cancer survivors know the journey is often overwhelming. National Cancer Survivor’s Day brings survivors and their families together in a wellspring of support.

    HOW TO OBSERVE #CancerSurvivorsDay #NCSD2020

    Each year, communities, hospitals and support groups host events and celebrations around the United States honoring cancer survivors. Events may include parades, carnivals, art exhibits, contests, and testimonies. President George W. Bush and the National Cancer Institute director each included a commencement at the 2008 celebration. Attend an event or organize one to show your support. Other ways to celebrate include:

    • Post a photo on social media showing your support for cancer survivors.
    • Share your story, journey of cancer survivor-ship.

    Use #CancerSurvivorsDay or #NCSD2021 to post on social media.


    Merril Hastings announced the first National Cancer Survivor’s Day during the second national conference meeting of the National Coalition for Cancer Survivor-ship in Albuquerque, New Mexico on November 20, 1987. Hastings then filed the name as an International Class 042 Service and also registered it with the United States Patent and Trademark Office in the name of Pulse Publications. The first observance was held on June 5, 1988.



    Every year on June 6th, we recognize the fun holiday, National Yo-Yo Day. The day celebrates the iconic stringed toy that generations have enjoyed. June 6th is the perfect day to get out your yo-yo’s and try your hand at The Sleeper, Walk the Dog, Shooting the Moon, Around the World or Hop the Fence.

    The yo-yo is an object consisting of an axle connected to two disks and a length of string looped around the axle. It is played by holding the free end of the string, allowing gravity or the force of a throw to spin the yo-yo and unwind the string, then allowing the yo-yo to wind itself back again. The activity is called “yo-yoing.”

    It is believed the yo-yo was first invented in ancient Greece. A Greek vase painting from 500 BC displays a boy playing with a yo-yo.

    The Yo-Yo in the United States

    The yo-yo came to the United States through a young boy by the name of Pedro Flores. When he immigrated to the United States from the Philippines as a young boy, he recalled playing with a toy called a bandalore. The toy inspired Flores to create a business, and he called it the Flores Yo-yo. Between 1928 and 1932 the Yo-yo Manufacturing Company operated in Santa Barbara, California. Flores later sold his companies to Donald F. Duncan.

    Donald F. Duncan, Sr. made the yo-yo popular in America when he manufactured the Duncan Yo-Yo in the early 1900s. He first trademarked the name “Yo-Yo” in 1932.

    • In 1999, the National Toy Hall of Fame elected the Duncan Yo-Yo into its halls at The Strong in Rochester, New York.
    • The National Yo-Yo Museum is located in Chico, California.
    • The term yo-yoing is also often used to describe a person fluctuating between two difficult decisions.
    • Collectors often spend hundreds of dollars on rare, vintage, and retro yo-yos.

    HOW TO OBSERVE #NationalYoYoDay

    Test your yo-yoing skills by trying as many yo-yo tricks as possible. Do you know how to do the pinwheel or walk the dog? Other ways to celebrate the day include:

    • Picking up a new yo-yo.
    • Learning a new yo-yo trick.
    • Starting a yo-yo collection or adding to one you already have.
    • Posting photos of your yo-yo collection.
    • Teach someone how to do a complex yo-yo trick such as the Double or Nothing.
    • Host a yo-yo competition.

    Show us your best yo-yo tricks using #NationalYoYoDay by posting on social media.


    Founded in 1990 in Arcade, NY by Daniel Volk, National Yo-Yo Day celebrates the yo-yo on June 6th, the date of Donald F. Duncan’s birth in 1892. Volk once worked for Duncan Toy Company as a talented yo-yo demonstrator from 1976-1978, touring the western part of the United States. As a result, Volk had the opportunity to impart some of his yo-yoing wisdom to two talented comedians. The Smothers Brothers later produced The Yo-Yo Man Instructional Video. Mr. Volk demonstrates right along with the comedians in the video, too. In conjunction with National Yo-Yo Day, the Hummingbird Toy Company produced the first of several Smothers Brothers brand yo-yos.



    Each year on June 6th, National Applesauce Cake Day recognizes a delicious and easy treat. This tasty applesauce cake offers an opportunity to share a slice (or two) of a cake that comes in a variety of recipes.

    When it comes to applesauce cake, mixing in spices, nuts or dried fruit makes this cake a crowd-pleaser, too. Cinnamon, nutmeg, and allspice are just a few spices to choose from. You might also like to add pecans or walnuts for some crunch. Raisins or chopped apples add a little extra natural sweetness and texture to this cake. Some bakers use homemade applesauce, but store-bought will do, too.

    In any cake recipe, applesauce may be substituted for the butter or oil for a healthier alternative. It is also said that one-half cup of applesauce may be substituted for one egg in some baking recipes for those who have egg allergies. 

    HOW TO OBSERVE #ApplesauceCakeDay

    Bake an applesauce cake to share. Don’t hesitate to try a new recipe or to share one of your favorites. It’s one of the best ways to celebrate. Wrap up a few slices and deliver them to your neighbor or bring them to work. We even have a few recipes for you to try.

      On June 6th we can see clearly and look good doing it as we celebrate National Eyewear Day.

      Spectacles have been around for about seven centuries, but early versions were only worn by monks and scholars. It wasn’t until the invention of the printing press in 1452 and an increase in literacy that the demand for eyewear grew as well.

      Eyewear today not only improves our vision, but it also protects it while adding elements of style and personality.  Imagine John Lennon without his iconic round frames.  Would Maverick be Top Gun without his aviators? No one would recognize Harry Caray without his trademark face-covering frames. Eyewear can define, outline, and punctuate a personality.  It can also be a little covert. Who is Clark Kent without his frames after all?  Though many may have tried, no one wore the dark tortoise shells better than Audrey Hepburn.

      Clearly, eyewear plays a significant role in our lives.  From improving vision and protection to providing a variety of style options, it certainly is something to celebrate on National Eyewear Day.

      HOW TO OBSERVE #NationalEyewearDay

      Wear your favorite eyewear. Whether they are for clearer vision, protection or just to change up your style, eyewear proves to be versatile in many ways. Show off your personality with a new set of frames or change up your look by swapping out old lenses. There are so many ways to celebrate. Show us your eyewear style by using #NationalEyewearDay to share on social media.


      Zyloware_WAZ_blueZyloware Eyewear founded National Eyewear Day in 2016 to celebrate the benefits of improved vision and the many styles available. The Registrar at National Day Calendar proclaimed the day to be observed on June 6th, annually.

      Zyloware Eyewear was founded in 1923 by Joseph Shyer and has been family-owned and operated for 93 years. The company prides itself on quality, service, and customer satisfaction.



National Higher Education Day on June 6th each year aims to prepare a path for more students toward a higher education degree.

Exponential costs of higher education and the United States opportunity gap have turned a college degree into something of a luxury for many Americans. Guiding and motivating future college students through the process of preparing for higher education will help increase their chances of graduating with a degree. The observance is designed to educate and inspire students. For more information, please visit

It is my desire to have a National Higher Education Day to educate and promote the many different ways students can fund their education. By having a National Day I will be able to inspire students of all ages to never give up on their dream of receiving a higher education degree!  Izamar Olaguez, founder of National Higher Education Day.

  • Expense – The cost of going to college continues to rise.
  • Indecision – Many students change their major multiple times during their college career.
  • Family – Commitments to family conflict with their educational goals.
  • Unprepared – The coursework is more difficult than their current abilities have prepared them for.
  • Mental health – They don’t have solid coping skills for the stressors of academic life.

The observance encourages students, educators, and families to tackle some of the issues of higher education head-on. By preparing students in all areas of their life, finding financial resources, addressing their educational goals, as well as focuses on their total health and well-being, students will look forward to a successful high educational career path.

HOW TO OBSERVE #NationalHigherEducationDay

Celebrate by advocating for higher education on your social media sites. Post photos about what level of education you have received and what future academic goals you have. Advocate for any funding opportunities and developing tools for a solid higher education experience. Use #NationalHigherEducationDay. We would also like to encourage you to donate to a scholarship program today!


In February of 2015, Izamar Olaguez and March Hronis founded National Higher Education Day to help prepare students for and increase their opportunities for higher education. The national spokesperson is Tamera Allard.

The Registrar at National Day Calendar declared the day to be observed annually on June 6th, annually



National Drive-In Movie Day on June 6th each year commemorates the day the first drive-in theater opened. Richard M. Hollingshead Jr. of Camden, New Jersey created the drive-in theater and he opened the first one on June 6, 1933.

At this first drive-in theater, the screen was 40 feet by 50 feet and there were 400 car slots. The advertising slogan used was, “The whole family is welcome, regardless of how noisy the children are.”  An Adolphe Meniou film, Wife Beware, was the first film shown. The idea caught on quickly and drive-ins began to pop up in other areas, too. By the late 1950s, approximately 4,000 drive-ins dotted the United States.

According to, New York, Pennsylvania, and Ohio have the best opportunity for movie viewing under the stars. Copiague, Long Island, New York once was home to one of the largest drive-in theaters. The drive-in covered over 29 acres and could park 2,500 vehicles. It also hosted a full-service restaurant with rooftop seating, a trolley system to take children and adults to the playground, and a large indoor theater in case of bad weather.

However, the invention of color television, VCRs, and video rentals along with the increase in land values and the widespread adoption of daylight saving time, led to a sharp decline in the drive-in popularity.

For a comprehensive list of drive-in theaters still in operation today, visit for locations by state.


Get a carload of friends and head to the drive-in. It’s movie time! You can also explore drive-in movie history. Share your drive-in movie memories with us. What was your first drive-in movie? Do you remember? What was the last drive-in movie you saw? Give a shout out to the drive-in movie theaters near you, and use #DriveInMovieDay to post on social media.


National Drive-In Movie Day, honors the opening day of the first drive-in. The creator of this day is unknown. However, check out these other great movie-themed celebrations on the calendar:

June 6th Celebrated (and Not So Celebrated) Birthdays
Nathan Hale – 1755

In 1776, at the age of 21, Captain Nathan Hale volunteered to carry out a mission ordered by General George Washington. Hale was charged with gathering information on the British troops. When the British revealed the Patriot’s identity, they swiftly placed a noose around Hale’s neck. According to legend, Hale declared before being hung, “I regret that I have but one life to give for my country.”

Sarah Parker Remond – 1826

Born into freedom, the African-American abolitionist and suffragist spoke to audiences around the world. In 1853, a theatre owner denied Remond and two of her two companions entry to the Opera, and the police responded. Remond brought charges against Henry Palmer, the theatre operator, and C.P. Philbrick, the officer who responded. Judge Russell found for the plaintiff, ordering the theatre to “stand by their contract, and give to every ticket holder of whatever nation, color or condition, the place which he has brought.”

David Scott – 1932

The American astronaut flew several missions during the space race, including a 1971 Moon landing. During the mission on July 31, 1971, Scott drove the Lunar Roving Vehicle, becoming the first person to drive on the Moon.

Phillip A. Sharp – 1944

In 1993, American molecular biologist Phillip Sharpe and Richard J. Roberts shared the Nobel Prize for Physiology or Medicine. Their study of DNA and split genes inspired new research into mRNA and evolutionary biology.
