    National Living Donor Day on April 11 celebrates and honors the brave people who step up and save lives by donating their living organs and tissue to heal those in need.


    According to, there are over 104,000 people in the United States on the national transplant waiting list. National Living Donor Day presents an opportunity to educate and encourage people to consider saving a life through living organ or tissue donation.

    April is already recognized as National Donate Life Awareness Month. While the monthly celebration generates a positive impact on saving lives, the focus tends to encourage individuals to sign up with the deceased donor registry to donate upon death. However, there is a significant opportunity to complement these initiatives by designating a specific day during the month of April that focuses on raising awareness of living organ donation. By bringing awareness to National Living Donor Day, we can demonstrate the importance of living donors by saving as many lives as possible by using living donor transplants.

    What Is Living Organ Donation?

    A living organ donation is a medical procedure that removes a healthy organ, portion of an organ, or tissue from a living person. The organ is then transplanted into another person whose organ is no longer working properly. Living organ donation allows the recipient to live a longer and healthier life. In addition, the donor contributes to the life of another to continue their own personal journey.

    Finding an organ donor can be a difficult process for many. Organ donation does not discriminate and those in need of a donation include people of every age, race, and gender. In fact, the demographic is so diverse, no specific category fits one person. Some people may wait for years for a deceased donor. However, living donors can alleviate and often eliminate the stress of waiting or wondering if an organ donation will happen before it’s too late.

    Who Can Be A Living Donor?

    Anyone can sign up to be a donor. Medical tests can help determine which recipient would benefit from your donation. Oftentimes, people misunderstand who qualifies to become an organ donor. An organ donor can be:

    • Anyone between the ages of 18 – 60 years of age at most transplant centers.
    • A parent, sibling or adult child.
    • Other relatives, such as an uncle, aunt, or cousin.
    • A biologically unrelated person who knows the recipient, such as a friend, co-worker, significant other, or spouse of a friend.
    • Anyone who knows the recipient’s need for the organ.
    • A good Samaritan living donor simply decides to donate because they are a match to a stranger who is in need of an organ.

    Many people wonder what makes for a good living donor candidate. Generally speaking, a good candidate is someone who has been mentally and physically healthy throughout their life. However, there are other factors that go into deciding if you should become a living donor. Ultimately, the decision is up to you. Some living donors want to be a part of something meaningful, while others have a personal interest in why they choose to be living donors. Whether the living donor chooses to help for charitable reasons or because they believe in a specific organization, living donors save lives.

    “If National Living Donor Day only saves a single life, it still will be worth it as it will give that individual a second chance at life and allow them to make special memories with friends and families that would not have otherwise been possible.”

    Dave Galbenski, Founder, Living Liver Foundation

    The 4-1-1 of Living Donors

    In 2022, there were 5,863 living donor kidney transplants comprising approximately 23% of kidney transplants in the U.S. In addition, there were 603 living donor liver transplants comprising approximately 6% of liver transplants in the U.S. By increasing the number of living organ donors, the transplant wait list has the potential to be eliminated, ensuring that no one dies while waiting for the availability of a deceased organ.

    The most common type of living donation is kidney donation, where a donor donates one of their kidneys to a recipient. The second most common is liver donation, where a donor donates a portion of their liver to a recipient.

    A major area of opportunity with living organ donation awareness is to educate the general public on the magical capability of the human liver. A significant amount of people in the U.S. are unaware that the liver is the only human organ that can regenerate. Not only does it regenerate in the donor to full size, but it also regenerates to full size in the recipient. Proof that combining the innate capabilities of the human body with innovative ideas from the human mind can result in modern medical miracles.

    For most living donors, the cost of testing, transplant surgery and follow-up care is covered by the recipient’s health care insurance.


    • Visit with your physician to begin the steps to becoming a living donor.
    • Support organizations that help find matches for those on the national donor list.
    • Help out a family who is recovering from a donor surgery.
    • Hold a fundraiser to alleviate costs for a living donor or recipient of a donor surgery.
    • Learn about the different types of organs and tissue a living donor can give.
    • Honor and support the transplant medical professionals and health systems that make living organ donation possible.
    • Share your story about becoming a living donor or receiving an organ donation on social media using #NationalLivingDonorDay.


    In 2023, the Living Liver Foundation and National Day Calendar formed a working collaboration to celebrate National Living Donor Day on April 11 each year. The day celebrates and honors the brave people who step up and save lives by donating their living organs and tissue to heal those in need. Dave and Lynn Galbenski, founders of the Living Liver Foundation, are asking for our help to spread the word and encourage living donor transplants. We share their goal to save the lives of up to 17 people per day that might otherwise die while on the transplant list.

    The Story Behind National Living Donor Day

    On November 25, 2019, Dave Galbenski underwent a successful living donor liver transplant at Henry Ford Hospital in Detroit, Michigan. Thanks to the courage, compassion, and generosity of his brother-in-law, Mark Dybis, who stepped forward to become his living liver donor. From that moment, Dave made a commitment to use his time, talents, and energy to promote living donor awareness to pay this tremendous gift of life forward.

    In 2020, Dave and Mark began to publicly tell their story to raise awareness of the impact of living organ donation. By providing key information and resources about living organ donation, Dave and Mark are inspiring others to potentially consider becoming a living donor.

    National Submarine Day, on April 11th, honors the day the United States Navy acquired its first modern commissioned submarine. On April 11, 1900, the Holland VI became the Navy’s first modern submarine.


    Designed by Irish-American inventor John Phillip Holland in 1896, he launched the Holland VI on May 17, 1897, at Navy Lt. Lewis Nixon’s Crescent Shipyard in Elizabeth, New Jersey. The United States Navy later purchased the Holland VI on April 11, 1900. As the military’s first commissioned submarine, the Navy renamed it the USS Holland (SS-1). 

    The U.S. Navy’s first submarine was the Alligator, 1862.

    Submarine history runs deep in the United States. During the Revolutionary War era, David Bushnell built America’s first submarine, the Turtle. The submersible made several attempts to sink British ships but never succeeded. At the time, the U.S. Navy did not exist, so the Turtle was not the Navy’s first submarine. The first known U.S. Navy submarine was the USS Alligator. It’s also the fourth United States Navy ship of that name. The Alligator was active during the American Civil War. 

    Elsewhere in the world, Submarine Day is celebrated on March 17th.

    In 1969, Senator Thomas J. Dodd (D-Conn.) introduced a bill (S. 2690) to the U.S. Senate to designate April 11th as National Submarine Day. While the bill passed the Senate and was introduced to the House in 1970 (H.R. 7998), no record of a proclamation from President Richard Nixon is found. Despite that, beginning in 1970, veteran organizations, U.S. Navy service members, and many other organizations recognized the day, commemorating the Navy’s first modern commissioned submarine. 

    Submarine FAQ

    Q. Are submarines only used for military purposes?
    A. No. Submarines are used in archeology, ocean exploration, salvage operations, and tourism.

    Q. Do you have to equalize the pressure in your ears as you submerge or surface in a submarine?
    A. No. The solid hull is pressurized to equalize the pressure in the submarine, eliminating the “popping” might feel while diving or flying in a plane. However, your ears might equalize or “pop” when the hatch is closed before submerging and again when the hatch is opened at the surface.

    Q. What is the world’s largest submarine?
    A. The world’s largest submarine is the Typhoon-class submarine. Part of the Soviet Navy, it is a nuclear-powered ballistic missile submarine.

    Q. What is the longest a submarine has been submerged?
    A. In 1983, Britain’s nuclear-powered submarine named the HMS Warspite spent 111 days submerged. The submarine descended on November 25, 1982, and resurfaced on March 15, 1983.




    Observed annually on April 11th, National Cheese Fondue Day recognizes a food holiday many enjoy. Fondue is a dish of melted cheese or other ingredients, served in a communal pot (caquelon) over a small portable stove (réchaud).  Participants then dip the bread into the cheese using long-stemmed forks. Cheese fondue consists of a blend of cheeses, wine, and seasoning.


    A 1966 book published in Zurich, under the name “Kass mit Wein zu kochen” is known for having the earliest known cheese fondue recipe. It calls for grated or cut up cheese melted with wine and for the bread dipped into it.

    The first known recipe with cheese and wine was published under the name “Cheese Fondue” in 1875.

    Cornstarch may be the reason the Swiss became so fond of fondue. In 1905, the thickener was introduced to the land of Switzerland. As many may know, cornstarch thickens liquid and makes smooth and creamy gravies. It also creates a smooth and stable emulsion of the wine and cheese.


    • Whip up a cheese fondue.
    • Invite friends and family (near and far) to join you with their own versions.
    • Host an online celebration and catch up with friends.
    • Discover how they celebrate with cheese fondue and make a toast to good times.
    • Share recipes, and if you don’t have one, we found a recipe for you to try.
    • Enjoy this delicious Creamy Cheese Fondue recipe.
    • Use #NationalCheeseFondueDay to post on social media.


    National Day Calendar continues researching the origins of this dairy food holiday. 

    Fondue FAQ

    Q. Besides cheese, what other ingredients can be used as a fondue base?
    A. While cheese fondue is quite popular, several other kinds of fondue add a savory (and sweet) twist to the subject. Try these:

    • Oil – Seasoned oil is heated in the fondue pot. Dip meats, breads, and vegetables.
    • Tomato – Seasoned tomato sauces serve as a base for delicious dipping.
    • Chocolate – Indulge in a creamy, chocolate treat by dipping fruit, sweet cheeses, and pastries into melted milk chocolate.

    Q. Q. What are the etiquette guidelines for cheese fondue?
    A. Since the fork you are using will be dipped in the shared pot many times, one of the most important rules is to never touch your mouth or lips to the fork. Use your dinner fork to remove the morsel to your plate.

    National Eight Track Tape Day on April 11th recognizes an era that was here and gone in a short 20 years. Nevertheless, it is a day to remember listening to great music of the sixties and seventies on eight-track tapes.


    Popular from the mid-1960s through the early 1980s, eight-track tapes are a magnetic tape sound recording technology.

    In 1964, Bill Lear of Lear Jet Corporation, along with Ampex, Ford Motor Company, General Motors, Motorola, and RCA, created the eight-track tape. Also known as Stereo 8, the first player was released in 1965.

    In September of 1965, Ford Motor Company introduced factory-installed and dealer installed eight-track tape players as an option to buyers on three of its 1966 models – the Thunderbird, Mustang, and Lincoln. In addition, Ford offered an eight-track tape player in all its vehicles as an upgrade option on the 1967 model. Through the 1980s, optional eight-track players were available in many cars and trucks.

    Eight track cartridges were phased out in the retail stores in the United States by late 1982. However, some titles were still available as eight-track tapes through various mail-order clubs until late 1988.

    Many of the late period eight-track tape releases are highly collectible today.


    • Listen to your eight-track tapes.
    • Share your favorite tracks.
    • Post a memory about playing eight tracks.
    • Share your enthusiasm for eight tracks and what makes you collect them.
    • Do you know someone who would enjoy this celebration? Be sure to let them know using #EightTrackDay to post on social media.

    On April 11th, toes start tapping to four-part harmony thanks to National Barbershop Quartet Day. Barbershop quartets have a way of making the heart flutter. Very often, they transport us back to a simpler time or at the least make it standstill.  


    Barbershop quartets are a style of a cappella or unaccompanied vocal music. Their music features songs with understandable lyrics and easily singable melodies.  

    Between 1900 and 1919, barbershop music found its popularity. In the 1920s, it began to fade into obscurity. However, the barbershop quartet saw a revival when the Society for the Preservation and Encouragement of Barber Shop Quartet Singing in America was founded. This tongue twister of a men’s organization quickly grew, as did other similar organizations promoting barbershop music as an art form. Today, just under 25,000 men in the United States and Canada are members of the SPEBSQSA.

    But men aren’t the only ones singing four-part harmony. Across the country, organizations like the Sweet Adelines bring women of all ages together, melding their voices together and making crowds swoon to fun tunes. Much like the men’s organizations, the women also compete. They tune their voices and rehearse while also performing locally. 


    • Do you have the pipes to harmonize with a quartet? Join a barbershop organization near you. Lend them your voice! You never know who you will meet or whose life you might impact with your music. 
    • Attend a barbershop event. They host performances throughout the year and provide excellent (often humorous) entertainment, too!
    • Learn more about the history of the barbershop quartet. Read Four Parts, No Waiting by Gage Averill, or watch the documentary American Harmony directed by Aengus James.
    • Read about On the Brink, a barbershop quartet out of Bismarck, North Dakota in Celebration Voices.
    • Use #BarbershopQuartetDay to post on social media.
    • Educators, visit the National Day Classroom for more information designed for the classroom.


    The birthday of the Society for the Preservation and Encouragement of Barber Shop Quartet Singing in America is April 11, 1938, in Tulsa, Oklahoma. Founded by Rupert I. Hall and Owen Clifton Cash, prospective members were not even required to be able to sing.  According to an article in a June 13, 1938, issue of the St. Louis Post-Dispatch, Cash was quoted as saying, “All we ask is just that said prospective member THINK he can sing.” 

    Barbershop Quartet FAQ

    Q. Do you have to be a barber to be in a barbershop quartet?
    A. No. While the phrase reflects the history of the music, you do not have to be a barber to be in a barbershop quartet.

    Q. Why is it called a “barbershop” quartet?
    A. There was a time when barbers supplied their own improvisational music to their customers, and it was called barbershop music. In the United States, barbershops formed social clubs that eventually gave way to acapella-style singing groups.

    Q. What is four-part harmony?
    A. In barbershop music, four-part harmony is a type of song written for four voices. In a barbershop quartet, each singer performs one of the four parts without instrumental accompaniment.

    Q. Do barbershop quartets choreograph steps to go with their songs?
    A. Many barbershop quartets include choreography in their performances. The addition of choreography provides a visual component and enhances the overall enjoyment of the performance.
