National & International Days on November 10
Area Code Day highlights how the simple three-digit system revolutionized telephone communication and laid the groundwork for today’s interconnected world. Introduced by AT&T and Bell Laboratories in 1947 as part of the North American Numbering Plan, it made direct long-distance dialing possible without operator assistance. The first call using an area code took place on November 10, 1951, when a connection was made from Englewood, New Jersey, to Alameda, California.
International Accounting Day recognizes the work of accountants and financial professionals around the world. The date marks the anniversary of Summa de Arithmetica, published in 1494 by Venetian mathematician Luca Bartolomeo de Pacioli, who is often called the Father of Accounting for describing the double-entry bookkeeping system still in use today. The first official celebration took place in 1972, organized by the San Diego chapter of the California Society of CPAs, and it has since grown into a global observance recognizing the vital role accountants play in maintaining financial transparency, integrity, and trust in every sector of society.
National Civic Pride Day inspires people to take pride in where they live and do something good for their community. It was started in 2017 by Project FrontYard in Lafayette, Louisiana, to encourage everyone to keep their towns clean, beautiful, and welcoming. The day reminds us that small actions—like picking up litter, planting flowers, or helping a neighbor—can make a big difference when everyone takes part.
National Forget-Me-Not Day supports disabled veterans and ensure their sacrifices are remembered. The day was created in 1921 by Judge Robert S. Marx, a World War I veteran who also founded the Disabled American Veterans (DAV). The small blue forget-me-not flower became the organization’s emblem, symbolizing remembrance and compassion. Volunteers sold these flowers to raise money for veterans whose needs exceeded available care after the war.
National Vanilla Cupcake Day celebrates the classic vanilla cupcake. The many other cupcake-related observances throughout the year show just how much people enjoy this delightful little cake in all its variations.
Odd Socks Day 🇬🇧* (Second Monday in November) s observed in the United Kingdom on the first day of Anti-Bullying Week, which falls on the second Monday in November. The day encourages children and adults alike to wear mismatched socks as a fun way to express individuality and remind everyone that our differences make us unique. Founded in 2017 by children’s TV presenter Andy Day and his band Andy and the Odd Socks, in partnership with the Anti-Bullying Alliance (ABA), the observance promotes kindness, acceptance, and respect in schools and communities across the UK.
Sesame Street Day commemorates the anniversary of the children’s television show that first aired in 1969. Created by Joan Ganz Cooney and Lloyd Morrisett of the Children’s Television Workshop (now Sesame Workshop), the program revolutionized early childhood education by combining entertainment and learning for preschoolers. Sesame Street helped children around the world learn numbers, letters, and social values such as kindness and inclusion. The day was first officially proclaimed in New York City in 2009 by Mayor Michael Bloomberg to celebrate the show’s 40th anniversary.
USMC Day (U.S. Marine Corps Birthday) / Death/Duty Day commemorates the establishment of the United States Marine Corps on November 10, 1775, when the Second Continental Congress created two battalions of Marines in Philadelphia. The date was officially declared the Corps’ birthday in 1921 by Major General John A. Lejeune, ensuring that Marines continue to celebrate their proud history and service each year.
World Immunization Day highlights the importance of vaccines in keeping people healthy and preventing the spread of dangerous diseases. Vaccination helps protect individuals and entire communities, saving millions of lives every year. The observance began around 2012 to remind the world that access to vaccines should be available to everyone, no matter where they live.
World Keratoconus Day raises awareness about keratoconus, a progressive eye condition that causes the cornea to thin and bulge into a cone shape, leading to blurred and distorted vision. Founded in 2016 by the National Keratoconus Foundation (NKCF), the day focuses on educating the public, supporting patients, and emphasizing the importance of early diagnosis and treatment options such as corneal cross-linking and specialized contact lenses.
World NET Cancer Day raises awareness about neuroendocrine tumors (NETs)—a rare and often misdiagnosed form of cancer. Because NET symptoms can mimic common conditions like asthma or irritable bowel syndrome, diagnosis is frequently delayed. The observance was founded in 2010 by the World NET Community Steering Committee and is now led by the International Neuroendocrine Cancer Alliance (INCA). Its “Think Zebras” message reminds doctors and patients to consider rare diseases when symptoms don’t fit typical patterns, promoting earlier detection and better outcomes.
World Science Day for Peace and Development emphasizes the importance of science in building a more peaceful and sustainable world. Proclaimed by UNESCO in 2001 and first celebrated in 2002, the day encourages global dialogue about how science shapes society, promotes international cooperation, and reminds governments and citizens alike of the need to use scientific progress responsibly for the benefit of all.
World Orphans Day* (Second Monday of November) raises awareness of the struggles faced by orphans and displaced children around the world. Founded by Cheryl Piggott of The Stars Foundation, the day encourages global action to support children who have lost one or both parents and often lack access to education, healthcare, and protection. Separate from the April 20 observance created by the Worldwide Organization for Charity, this November day serves as a reminder of the millions of children who need care and opportunities for a better future.
World Top Up Day celebrates the kindness of people who send mobile credit to loved ones abroad. Founded in 2015 by MobileRecharge.com, the observance recognizes how immigrants and expatriates use mobile top-ups to stay connected with family and friends.
