National & International Days on November 7, 2026
Below are brief explanations of each observance celebrated on November 7.
International Day of Medical Physics
International Day of Medical Physics honors the work of medical physicists—the experts who apply physics to medicine to improve diagnosis and treatment. These professionals ensure that radiation and advanced technologies are used safely and effectively in areas such as X-rays, MRI scans, and cancer therapy. The observance was established by the International Organization for Medical Physics (IOMP) and is held on this date to mark the birthday of Marie Skłodowska-Curie, born in 1867, whose groundbreaking research on radioactivity laid the foundation for modern medical physics.
International Hug A Bear Day
International Hug A Bear Day encourages people to share friendly “bear hugs” or cuddle their favorite stuffed bear. Teddy bears, first created in the early 1900s, have long symbolized love, security, and childhood comfort. This observance highlights how something as simple as a hug can lift the spirit, reduce stress, and strengthen emotional connection.
International Merlot Day
International Merlot Day pays tribute to the Merlot grape, a classic red variety known for its smooth texture and enjoyable flavor. Originating in France’s Bordeaux region, Merlot remains the most widely planted grape there and plays a key role in many well-known blends. Its name likely comes from the French word merle (“blackbird”), referring to the grape’s dark color or to birds’ fondness for the fruit. With flavors of plum, cherry, and blackberry, Merlot remains one of the most popular red wines to share at the table.
National Bison Day
National Bison Day* (First Saturday in November) celebrates the American bison, an animal deeply connected to the nation’s history, culture, and natural heritage. Once nearly wiped out in the 1800s, the bison has made a remarkable recovery thanks to conservation efforts led by Indigenous communities, ranchers, and wildlife organizations. The observance draws attention to the animal’s role in maintaining healthy grasslands and reminds people of its cultural importance. The U.S. Senate began recognizing the day in 2013, and in 2016 President Barack Obama signed the National Bison Legacy Act, officially naming the bison the national mammal of the United States.

National Canine Lymphoma Awareness Day
National Canine Lymphoma Awareness Day raises awareness about one of the most common cancers in dogs. The day helps pet owners recognize early symptoms, understand available treatments, and learn how to support dogs affected by this illness. It was founded in 2015 by dog agility trainer Terry Simons after his own dog, Reveille, was diagnosed with lymphoma in 2011. To honor Reveille’s journey and help others facing the same challenge, Simons created the CLEAR (Canine Lymphoma Education Awareness and Research) Foundation, which continues to provide education and resources about this serious but treatable disease.
National Programmatic Advertising Day
National Programmatic Advertising Day recognizes the people behind automated digital advertising—the technology that decides which ads appear online and when. Founded in 2019 by Adelphic by Viant, a company specializing in programmatic advertising tools, the day honors the analysts and marketers who use data and algorithms to make online advertising more efficient and relevant. It also helps raise awareness of how programmatic technology shapes the ads we see across websites, videos, and apps, making it an essential part of today’s digital marketing world.
National Retinol Day
National Retinol Day celebrates one of skincare’s most trusted ingredients—retinol, a form of Vitamin A known for its powerful anti-aging benefits. The day was founded in 2021 by RoC Skincare to mark the 25th anniversary of RoC’s innovation in stabilizing retinol for everyday use. The observance aims to educate people about how retinol helps renew skin cells, smooth fine lines, even out tone, and support collagen production, making it a key ingredient in many dermatologist-recommended skincare routines.
Notary Public Day
Notary Public Day honors the trusted professionals who help protect the public from fraud and ensure the authenticity of important documents. Notaries serve as impartial witnesses, verifying identities and confirming that signers understand and willingly agree to what they’re signing. The observance was established in 1974 by the American Society of Notaries (ASN), with the first celebration held in 1975. The date was chosen to honor Thomas Fugill, appointed on November 7, 1639 (modern calendar), as America’s first notary public in the Colony of New Haven.
World Numbat Day
World Numbat Day* (First Saturday in November) raises awareness about the numbat, a small, endangered marsupial found only in parts of Western Australia. This animal is known for its striking white stripes, bushy tail, and long, sticky tongue used to eat termites—its main source of food. Unlike most marsupials, the numbat is active during the day, which makes it more vulnerable to predators. The observance aims to protect this rare species and draw attention to conservation efforts that help ensure its survival.
