National & International Days on November 16
Below is a list of 10 national and international days celebrated on November 16, each with a brief explanation.
Have a Party with Your Bear Day
Have a Party with Your Bear Day celebrates the connection between children and their teddy bears, toys that have held a special place in childhood for over a century. The day recognizes how these familiar companions provide comfort, spark imagination, and have become so meaningful that several observances now honor them throughout the year.
International Check Your Wipers Day
National Check Your Wipers Day* (held twice a year in May and November) was founded in 2021 by Michelin North America to raise awareness about vehicle safety. The observance reminds drivers to inspect and replace worn windshield wipers, ensuring clear visibility in rain or snow. It’s held twice a year—November 16 in North America and May 16 in parts of Latin America—to align with seasonal weather changes and promote safer driving during busy travel periods.
International Day for Tolerance
International Day for Tolerance was established by the United Nations in 1996, following UNESCO’s adoption of the Declaration of Principles on Tolerance in 1995. The day promotes understanding, respect, and acceptance among people of different cultures, beliefs, and lifestyles. It also encourages education on human rights and peaceful coexistence. Every two years, UNESCO awards the Madanjeet Singh Prize for the Promotion of Tolerance and Non-Violence to honor individuals and organizations that advance these values worldwide.
National Black Marketers Day
National Black Marketers Day was created in 2021 by the Black Marketers Coalition (BMC) to celebrate and empower Black professionals in the marketing industry. The date was chosen to honor 1942, the founding year of Johnson Publishing, one of the first major Black media companies. The day highlights the influence of Black marketers in shaping culture and communication while promoting greater diversity and inclusion across the field.
National Button Day
National Button Day, established in 1938 by the National Button Society, highlights the role of buttons in history, design, and everyday life. It invites people to explore how buttons have evolved—from early handmade fasteners to modern manufactured pieces—and how they reflect changes in fashion, technology, and culture.
National Clarinet Day
National Clarinet Day highlights the clarinet’s important place in music history. First developed from the chalumeau by Johann Christoph Denner in the early 1700s, the clarinet has become a key instrument in classical, jazz, and orchestral music. The observance, which began in the 1980s, recognizes both the instrument’s evolution and the musicians who bring its sound to life.
National Fast Food Day
National Fast Food Day highlights how fast food has shaped modern life and eating habits. The term “fast food” was added to the Merriam-Webster dictionary in 1951, though the idea of quick, ready-to-eat meals dates back to ancient times. From White Castle, founded in 1921 as the first fast-food chain, to today’s global brands like McDonald’s and Taco Bell, the day reflects how convenience dining has influenced culture, business, and everyday routines around the world.
National Indiana Day
National Indiana Day highlights the history and culture of Indiana, which became the 19th U.S. state in 1816. Although its official statehood day is December 11, this observance offers an additional chance to explore Indiana’s role in American history, from its agricultural and industrial roots to its influence on music, sports, and education.
National Slobber Appreciation Day
National Slobber Appreciation Day was founded in 2012 by Jennifer from the blog My Brown Newfies in honor of her Newfoundland dogs, Irving and Maddie. The day aims to educate dog owners about breeds that naturally drool—such as Newfoundlands, Saint Bernards, and Mastiffs—and to promote understanding of this normal canine trait. By raising awareness, it helps prevent pets from being surrendered due to unexpected drooling and encourages acceptance of all the quirks that come with loving big, slobbery dogs.
Odd Socks Day
Odd Socks Day 🇬🇧* (Dates change annually) 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.
