National and International Days on June 5

Earth Overshoot Day* (Date changes yearly) marks the point when humanity’s resource consumption for the year exceeds what Earth can regenerate. The concept was introduced by Andrew Simms of the UK think tank New Economics Foundation and is now managed by the Global Footprint Network. While the actual date shifts each year based on ecological data, the announcement for the 2025 date is expected on June 5, aligning with World Environment Day. The day is a reminder to reconsider how natural resources are used and to advocate for sustainable living.

HIV Long-Term Survivors Awareness Day honors those who have lived with HIV for decades, acknowledging both their resilience and the unique challenges they face. First observed in 2014, this day takes place on June 5 to mark the anniversary of the CDC’s 1981 report that identified the first known cases of AIDS. It serves to raise awareness about long-term survivorship and the ongoing needs of those aging with HIV.

Illegal Fishing Day is officially recognized as the International Day for the Fight Against Illegal, Unreported and Unregulated (IUU) Fishing. Established by the United Nations General Assembly in 2017, it draws attention to the severe impact of IUU fishing on marine ecosystems, coastal economies, and food security. June 5 was chosen to coincide with the adoption of the Port State Measures Agreement, a global treaty targeting illegal fishing practices.

National Gingerbread Day may seem out of place in June, but this spicy-sweet celebration is welcomed year-round. Gingerbread can refer to cookies, cakes, or bars, all typically flavored with ginger, cinnamon, cloves, and sweetened with molasses or sugar. The tradition is thought to have been introduced to Europe in the 10th century by the Armenian monk Gregory of Nicopolis. Today, bakers across the U.S. take the opportunity on June 5 to enjoy or create their favorite gingerbread treats.

National Hot Air Balloon Day commemorates the early history of human flight, especially the achievements of the Montgolfier brothers who launched the first successful hot air balloon in France on June 4, 1783. The first manned flight followed later that year. Observed on June 5, the day celebrates ballooning as a recreational and historic mode of flight, offering a unique way to appreciate the skies.

National Ketchup Day honors one of the most iconic condiments in American households. Ketchup’s history stretches back to 300 BC in China, where the original kê-tsiap was a fermented fish sauce. British sailors encountered it in Southeast Asia and adapted it to local ingredients. In 1812, American James Mease documented the first tomato-based version, and H.J. Heinz later popularized the version we know today. June 5 celebrates this sweet and tangy staple of everything from fries to burgers.

National Moonshine Day celebrates the tradition of high-proof, unaged liquor known for its rebellious past. The term “moonshine” dates to 18th-century British slang and gained notoriety in the U.S. during Prohibition. Today, the name is used by legal distillers to evoke its rich and sometimes outlaw-themed heritage. Observed on June 5, the day reflects on the cultural and historical significance of moonshine in American history.

National Sausage Roll Day was founded in 2015 to honor this savory dish of sausage meat wrapped in puff pastry. While sausage rolls are popular throughout Europe, they are especially beloved in the UK, where they became a culinary staple during the Napoleonic Wars. June 5 invites people to enjoy both traditional and plant-based versions of this classic comfort food.

National Veggie Burger Day was founded in 2017 by Amy’s Kitchen to promote plant-based eating and showcase how veggie burgers can be both delicious and sustainable. Observed every June 5, the day encourages people to try a veggie burger and reflect on the positive impact that plant-based diets can have on personal health, animal welfare, and the environment.

🥬 It pairs well with other food holidays like National Vegetarian Day on October 1 and World Vegan Day on November 1.

Random Acts of Cardness Day began in 2015 with the creation of the Random Acts of Cardness Facebook group, founded by Megan Evans during her recovery from a traumatic brain injury. On June 5 each year, participants are encouraged to brighten someone’s day by sending a thoughtful greeting card.

This heartfelt observance is not tied to any commercial brand—it simply promotes kindness, connection, and healing, similar in spirit to Random Acts of Kindness Day (February 17).

Women Chiropractors Day highlights and honors the contributions of female chiropractors in a field that has historically been male-dominated. Celebrated on June 5, the day coincides with educational events and gatherings like those held by Life University’s Chiropractic Assembly.

Established by the United Nations in 1972 and first held in 1974, the day is observed on June 5 each year. It serves as a platform to raise global awareness about issues like pollution, biodiversity loss, climate change, and sustainable development. With worldwide participation from governments, organizations, and individuals, the day promotes a collective effort toward a healthier planet.
