National and International Days on June 11

International Lynx Day: First celebrated in 2019, International Lynx Day was created to raise awareness about the conservation of lynxes and their habitats. These wild cats—including the Eurasian lynx, Canada lynx, Iberian lynx, and bobcat—are essential apex predators that help regulate ecosystems. Conservation groups and educators use this day to spotlight the threats these animals face, such as habitat destruction and poaching, and to encourage action to protect their future.

International Yarn Bombing Day: Launched in 2011 by Joann Matvichuk of Lethbridge, Alberta, this day celebrates yarn bombing as a cheerful form of street art. Yarn bombing, or yarn graffiti, involves decorating public spaces with knitted or crocheted yarn to bring unexpected color and warmth to urban environments. Celebrated on June 11 each year, it fosters community, creativity, and joy—without the controversy often associated with graffiti.

KBG Syndrome Awareness Day: First observed in 2016 and officially recognized by the KBG Foundation in 2017, this day helps bring attention to KBG syndrome—a rare neurodevelopmental disorder linked to the ANKRD11 gene. Only around 200 cases have been identified worldwide, making awareness and education especially important. June 11 was chosen to honor the discovery and help more families find support and information about this underdiagnosed condition.

National Corn on the Cob Day: This summery celebration shines a light on one of the season’s favorite foods. Corn has been cultivated for over 7,000 years, starting in Mexico before spreading across North America. Native American tribes played a major role in its early cultivation. Today, corn on the cob is a staple at cookouts and festivals, and June 11 serves as a perfect excuse to enjoy it grilled, boiled, or roasted.

National German Chocolate Cake Day: Despite its name, this layered dessert originated in the United States, not Germany. It’s named after Samuel German, who developed a type of sweet baking chocolate used in the original recipe. The cake gained national fame in 1957 when a Dallas newspaper published a version submitted by homemaker Mrs. George Clay. With its coconut-pecan frosting and rich history, this cake has become an American classic worth celebrating each June 11.
