National and International Days on July 18

Black Leaders Awareness Day was founded in the United Kingdom to recognize the wisdom and influence of Black leaders throughout history and into the future. It highlights voices from across generations—well-known figures like Martin Luther King Jr. and Maya Angelou, as well as emerging leaders of today and tomorrow. Through speeches, quotes, and shared media, the day encourages learning, reflection, and respect across cultures. July 18 was chosen in honor of Nelson Mandela’s birthday.

Insurance Nerd Day celebrates professionals in the insurance industry and was created in 2016 by Pioneer State Mutual Insurance Company. The goal was to change public perception of insurance careers, showing they can be dynamic and meaningful. By naming it “Insurance Nerd Day,” the founders embraced the passion and knowledge of those working in the field while encouraging young people to explore opportunities in this often-overlooked industry.

National Caviar Day puts the spotlight on sturgeon roe, considered a delicacy in many parts of the world. It also raises awareness about the endangered status of the sturgeon species. Caviar varies in color depending on the type of sturgeon, and it’s known for being rich in protein, omega-3s, and other nutrients. The day invites people to learn more about where caviar comes from, its ecological impact, and its place in culinary history.

National Dapper Your Data Day was launched in 2020 by Dapper Data, LLC to help people take control of their digital lives. It’s a reminder to review data, clean out digital clutter, and check privacy settings. The name brings a touch of style to tasks like organizing files, strengthening passwords, and staying cyber-aware. The day has since attracted attention from educators, businesses, and tech experts who encourage smarter data habits both online and offline.

National Sour Candy Day celebrates the tangy side of the candy world. Founded in 2015 by the American Licorice Company, the day invites everyone to enjoy sour candies and explore their history. Sour flavors go back to ancient uses of lemon juice and tamarind, but in candy, acids like tartaric and citric acid give that familiar puckering sensation. From Lemonheads to sour gummies, this day is a tribute to the science and fun taste behind sour snacks.

National Tropical Fruit Day highlights the colorful range of fruits that thrive in warm climates—from mangos and pineapples to dragon fruit and passionfruit. Celebrated since 2023, the day encourages people to try new fruits, learn about where they grow, and explore how tropical produce supports global agriculture. It’s also a great opportunity to support local markets and farmers who bring these fruits to tables around the world.

Nelson Mandela International Day was established by the United Nations in 2009 to honor Mandela’s legacy as an anti-apartheid leader and advocate for justice. Born on July 18, 1918, Mandela became South Africa’s first Black president and led efforts to dismantle apartheid and promote racial equality. In 2015, the UN expanded the day to include the Nelson Mandela Rules, which promote humane treatment of prisoners. The day encourages everyone to contribute positively to their communities in his spirit.

Perfect Family Day was introduced in 1999 through the efforts of several family-focused groups who wanted a day to encourage deeper connection at home. It’s a reminder to appreciate relationships and spend quality time together—no matter what form a family takes. Over time, more people began observing it through meals, games, conversations, or simple acts of appreciation. The day promotes love, respect, trust, and togetherness within families of all shapes and sizes.

World Listening Day is observed each year on July 18 to honor Canadian composer and environmentalist R. Murray Schafer, a pioneer in the field of acoustic ecology. Created in 2010 by the World Listening Project, the day encourages people to engage with their environment through sound. From field recordings to quiet reflection, it promotes listening as a cultural and ecological practice and invites people to consider how sound shapes the way we understand the world.
