National & International Days on October 20

Community Media Day highlights the importance of locally owned and accessible media that give people a voice in their own communities. The day was founded in 2016 by Alease Annan at Brooklyn Free Speech TV in New York to recognize the value of community-driven storytelling and its link to free expression. Community media outlets—such as local radio, television, print, and online platforms—are usually nonprofit and volunteer-based. They serve neighborhoods or specific groups, offering perspectives that larger commercial media often overlook. By doing so, they strengthen free speech, civic participation, and open dialogue on local and social issues.

Information Overload Day draws attention to the stress and fatigue caused by the constant flow of digital information in modern life. The day was founded in 2009 by analyst Jonathan Spira of the research firm Basex, after he identified information overload as the company’s “Problem of the Year.” The concept itself dates back to 1964, when political scientist Bertram Gross first used the term, and futurist Alvin Toffler later popularized it in his 1970 book Future Shock. The observance serves as a reminder to pause, set boundaries with technology, and manage the endless stream of emails, messages, and online updates that can make it difficult to focus and think clearly.

International Mastocytosis and Mast Cell Diseases Awareness Day raises awareness about a group of rare immune conditions caused by abnormal behavior of mast cells—immune cells that help the body respond to allergens and infections. When these cells build up or release chemicals too easily, they can trigger symptoms such as skin reactions, digestive problems, bone pain, and even severe allergic responses. The day highlights conditions like mastocytosis, mast cell activation syndrome (MCAS), and hereditary alpha tryptasemia (HaT), encouraging better understanding, diagnosis, and research. It was first marked in 2018 through a global collaboration of 24 advocacy groups.

International Chefs Day celebrates the art and profession of cooking while emphasizing education about healthy and sustainable food. Founded in 2004 by Dr. Bill Gallagher, president of the World Association of Chefs Societies (Worldchefs), the observance highlights the vital role chefs play in shaping how communities eat and think about food. Through partnerships such as the one with Nestlé Professional, the day also encourages chefs to share their knowledge with children, inspiring the next generation to explore ingredients, learn basic cooking skills, and make nutritious choices.

🧑‍🍳 A related observance, National Personal Chef Day on July 16, recognizes chefs who prepare customized meals in homes and for private clients.

International Day of the Air Traffic Controller recognizes the professionals who manage the safe and orderly movement of aircraft around the world. Air traffic controllers play a crucial role in preventing collisions, guiding pilots during takeoff, landing, and flight, and ensuring that air travel remains smooth and efficient. The day marks the founding of the International Federation of Air Traffic Controllers’ Associations (IFATCA) in 1961, an organization created to strengthen international cooperation and promote the highest standards of safety and professionalism in air navigation.

National Brandied Fruit Day honors the centuries-old European custom of preserving fruit—such as cherries, peaches, and apricots—by soaking it in brandy with sugar and spices. Originating in the 1600s as a way to keep fruit fresh through the winter, the practice soon gained popularity for the rich flavor it produced. Over time, brandied fruit evolved from a practical preservation method into a cherished ingredient in desserts, pastries, and festive dishes enjoyed across the world.

National Call-In Day for Health Reform encourages people to speak up about healthcare policies and contact their elected representatives to share their views. The goal is to show widespread public support for improving access, affordability, and quality of healthcare in the United States. Over the years, participants have focused on protecting programs like the Affordable Care Act, Medicaid, and Medicare, as well as opposing funding cuts and promoting laws that strengthen patient care. The day serves as a reminder that citizen voices can influence how health policies are shaped and implemented.

National Chicken and Waffles Day honors the famous mix of crispy fried chicken and sweet waffles, a dish with roots in two very different American traditions. It was created in 2021 by Roscoe’s House of Chicken ’N Waffles in California to celebrate the meal and encourage community service. The idea of serving chicken with waffles began with the Pennsylvania Dutch in the 1600s, who topped plain waffles with stewed chicken and gravy. Later, in the American South, cooks replaced the stewed chicken with seasoned, fried pieces, turning it into delicious dish. When Southern migrants brought their recipes north to cities like Harlem, the two styles came together, giving rise to the version enjoyed across the country today.

National Clean Your Virtual Desktop Day* (Third Monday in October) reminds people to tidy up their digital spaces just as they would a cluttered desk. The observance was started in 2010 by the Personal Computer Museum in Brantford, Ontario, Canada, to raise awareness about the benefits of keeping computers organized. Clearing old files, sorting folders, and removing unnecessary icons can make devices run faster and help users feel more focused and efficient. The day reminds us that a clean virtual workspace can improve both digital performance and peace of mind.

National Day on Writing highlights how writing shapes everyday life, from texting and journaling to storytelling and professional communication. Established in 2009 by the National Council of Teachers of English (NCTE), the day aims to show that writing is not limited to classrooms or authors but is a skill everyone uses to express ideas and connect with others. Over the years, the U.S. Senate has recognized the observance, and the #WhyIWrite campaign has become its central feature, inviting people of all ages to share what inspires them to write.

National Sasquatch Awareness Day recognizes the legendary creature known as Bigfoot, a central figure in North American folklore. The date was chosen to mark the anniversary of the 1967 Patterson-Gimlin film, which captured a brief video of a large, humanlike figure walking through Bluff Creek, California. Though the film’s authenticity remains debated, it became one of the most studied pieces of alleged Bigfoot evidence. The idea for an annual awareness day gained traction after a 2009 petition on Change.org proposed October 20 as a time to highlight the mystery, cultural impact, and ongoing interest in Sasquatch across the U.S. and Canada.

National Suspenders Day elebrates the long history and timeless style of suspenders—known as braces in Britain. The accessory was first introduced in 1822 by British designer Albert Thurston, whose early “H-back” model featured leather loops that fastened to high-waisted trousers, eliminating the need for belts. Originally worn as a hidden undergarment, suspenders eventually became a visible part of men’s fashion. Over time, they evolved into the familiar X- and Y-back designs made from silk, wool, and other materials. In 1871, author Mark Twain advanced the concept further by patenting adjustable, detachable suspenders with metal clasps, which made them far more practical for everyday wear.

National Youth Confidence Day focuses on helping young people believe in themselves and recognize their potential. Founded in 2018 by Tiffany R. Lewis, CEO of Confident Girl Mentoring Program, Inc., the day highlights the importance of mentorship, encouragement, and positive role models. It reminds adults to support youth through guidance and genuine connection, giving them the confidence needed to face challenges and grow into strong, capable individuals.

NBA Jersey Day* (Dates Change, October 20 in 2025) invites basketball fans worldwide to celebrate their love for the game by wearing their favorite NBA jerseys. As the NBA prepares for the upcoming season, this event encourages fans to join in the excitement by proudly displaying their team’s colors. To participate, fans can wear their jerseys and share photos on social media using the hashtags #NBAJerseyDay and #KiaTipOff25.

Office Chocolate Day encourages coworkers to take a short break, enjoy some chocolate together, and remember how small, shared moments can lift spirits and strengthen workplace connections.

Talent Transformation Day focuses on how technology is reshaping the way people work and the skills they need to succeed. Created in 2020 by the Talent Transformation Guild, a non-profit organization that supports workforce development, the day draws attention to the growing impact of artificial intelligence, automation, and robotics on jobs and business practices. It reminds both individuals and companies of the importance of ongoing learning, adaptability, and skill-building to stay prepared for the fast-changing world of work.

World CRISPR Day recognizes one of the most groundbreaking scientific discoveries of the 21st century. It was created in 2020 by the biotechnology company Synthego to highlight how CRISPR technology is changing the future of science and medicine. CRISPR—short for Clustered Regularly Interspaced Short Palindromic Repeats—is a gene-editing method that allows scientists to precisely change DNA. Originally discovered as part of a bacterial defense system, it was later adapted into a powerful research tool by Jennifer Doudna and Emmanuelle Charpentier, who received the 2020 Nobel Prize in Chemistry for their work. The observance marks the date when CRISPR was first used to edit a human genome, reminding people of how this discovery continues to shape research, agriculture, and the fight against genetic diseases.

World Osteoporosis Day focuses on raising awareness about bone health and preventing osteoporosis, a condition that weakens bones and increases the risk of fractures. The observance was first launched in 1996 by the United Kingdom’s National Osteoporosis Society and has been led by the International Osteoporosis Foundation since 1997. Often called a “silent disease” because it develops without clear symptoms until a fracture happens. Osteoporosis affects millions worldwide. The campaign aims to educate people about early prevention, healthy lifestyle choices, and the importance of diagnosis and treatment. It also marks the start of a year-long global effort to keep bone health high on public health agendas.

World Statistics Day* (celebrated every five years: 2025, 2030, 2035, 2040, 2045) highlights the importance of trustworthy data in shaping decisions and policies. Established by the United Nations General Assembly in 2010, the day recognizes the role of statistics in understanding social, economic, and environmental issues. It honors the Fundamental Principles of Official Statistics, a set of guidelines adopted by the UN in 1994 to ensure data quality, integrity, and accessibility. The 2025 theme, “Driving Change with Quality Statistics and Data for Everyone,” focuses on how reliable and inclusive data helps drive progress worldwide.
