Here’s the story behind every celebration on September 5, from Mother Teresa’s legacy to a plate of cheese pizza.
International Bacon Day
International Bacon Day* (Saturday before US Labor Day) began in the early 2000s, most often credited to three graduate students at the University of Colorado Boulder—Seth Rittenhouse, Evan Salim, and Alexa Halford—who launched it in 2004. They chose the Saturday before Labor Day to guarantee a weekend celebration, combining a humorous nod to a line from The Simpsons with their enthusiasm for bacon. What started as a playful student gathering quickly spread beyond campus, gaining momentum through social media and evolving into a worldwide event that celebrates bacon.
International Day of Charity
International Day of Charity was established by the United Nations General Assembly in 2012, inspired by the humanitarian legacy of Mother Teresa, who passed away on September 5, 1997. The day promotes charitable action and volunteerism as essential tools for fighting poverty and distress. It calls on individuals, communities, and organizations worldwide to take part in charitable activities and strengthen a global culture of compassion.
International Turkey Vulture Day (IVAD)
International Turkey Vulture Day (IVAD)* (First Saturday of September) was created in 2009 through collaboration between the Hawk Conservancy Trust in England and the Birds of Prey Programme in South Africa. Coordinated today by groups like the Vulture Conservation Foundation, it draws attention to vultures’ vital ecological role as nature’s cleanup crew and the severe threats they face from poisoning, electrocution, habitat loss, and illegal killing. Educational events and conservation campaigns help shift public perception of these misunderstood birds and highlight their importance in preventing disease and recycling nutrients.
National Actdumb Day
National Actdumb Day, founded in 2020 by the apparel brand Actdumb, promotes kindness through the idea of “acting dumb” in the sense of doing something simple, lighthearted, or unexpected to make someone else smile. The day reclaims the phrase as a positive message, encouraging compassion and acceptance while addressing the stigma historically attached to mental disability.
National Be Late for Something Day
National Be Late for Something Day was launched in 1956 by the Procrastinators’ Club of America as a playful rejection of over-scheduling and constant rush. It invites people to pause, slow down, and enjoy the present moment—even if it means arriving late. The observance humorously reframes tardiness as a chance to appreciate life at a more relaxed pace.
National Cellulite Day
National Cellulite Day, established in 2019, encourages acceptance and body positivity by normalizing cellulite, a natural condition affecting most women. The observance challenges beauty industry stigma and promotes the message that cellulite is not a flaw but a normal feature of human bodies. It also raises awareness about misleading “miracle treatments” and focuses instead on self-love and authenticity.
National Cheese Pizza Day
National Cheese Pizza Day celebrates one of the most popular forms of pizza, enjoyed for its simplicity and versatility. Pizza came to the United States with Italian immigrants in the late 19th and early 20th centuries, becoming especially popular in cities like New York and Chicago. A recorded “Cheese Pizza Day” event took place in 1965 in Ironwood, Michigan, though the modern observance spread much later as pizza grew into a cultural staple.
National Franchise Appreciation Day
National Franchise Appreciation Day* (Saturday before Labor Day) highlights the role of franchise businesses in local and national economies. The franchise model, which dates back to the Middle Ages, became especially prominent in the modern era as a way to expand business opportunities and provide employment. The day acknowledges the entrepreneurial spirit of franchisees and the support of franchisors. It also draws attention to the services and jobs franchises provide within their communities.

With more than 300 species worldwide, hummingbirds are celebrated for their beauty, agility, and vital role in pollination. The day encourages conservation, gardening with nectar-rich flowers, and education about the threats hummingbirds face from climate change and habitat loss.
National Shrink Day
National Shrink Day, observed on Bob Newhart’s birthday, September 5, honors both mental health professionals and the actor who played a psychiatrist on The Bob Newhart Show. It recognizes the vital role of psychiatrists, psychologists, and therapists in supporting mental well-being while celebrating how pop culture has helped normalize conversations about mental health.
Spinal Cord Injury Day
Spinal Cord Injury Day was declared on September 5 by the International Spinal Cord Society (ISCoS) to highlight not only the physical challenges of spinal cord injuries but also the social, psychological, and professional barriers individuals face.

World Beard Day
World Beard Day* (First Saturday in September) embraces one of humanity’s oldest symbols of identity and style. While the modern celebration became formalized in the 2010s, folklore links beard festivals to Viking traditions as early as 800 AD, particularly in Denmark. Today, the day is marked with beard competitions, themed events, and lighthearted gatherings that celebrate the diversity of facial hair and its cultural significance around the world.
World Samosa Day
World Samosa Day celebrates the triangular pastry with deep historical roots, tracing back to Middle Eastern sambusak brought to India by traders in the 13th or 14th century. Over time, the samosa became a South Asian staple, with countless regional variations in fillings and spices. The day honors both the global journey of this dish and its role as a beloved comfort food.
