National and International Days on September 7

Google Commemoration Day informally marks September 7, 1998, the date Google was officially incorporated in Menlo Park, California. From its beginnings in a garage, supported by early investor funding, the company rapidly grew into the world’s most widely used search engine. Today, this day recalls how Google transformed the way people access and share information, reshaping communication, business, education, and culture on a global scale.

International Day of Clean Air for Blue Skies was established by the United Nations in 2019, following a resolution proposed by the Republic of Korea, with the first observance held on September 7, 2020. The day highlights the dangers of air pollution, which affects both human health and climate change, and encourages nations to work together toward cleaner, healthier environments. Events emphasize the connections between air quality, sustainable development, and global well-being.

International Day of Police Cooperation was created by a 2022 UN General Assembly resolution to be observed every year on September 7. The date commemorates the founding of the International Criminal Police Commission (ICPC) in 1923, the predecessor to INTERPOL.

Observed on September 7, it acknowledges the expertise and hard work of technicians, builders, and service providers who ensure safe and enjoyable aquatic spaces for recreation and wellness.

National Acorn Squash Day celebrates the nutritious and versatile vegetable, a member of the Cucurbitaceae family. Native to North and Central America, acorn squash was cultivated for thousands of years by Indigenous peoples, who valued it as part of the “Three Sisters” agricultural system alongside corn and beans. European settlers adopted the crop and later introduced it to Europe. Its distinctive acorn-like shape and sweet, nutty flavor made it popular in a variety of dishes, from roasting to soups and purees. The day encourages people to explore its culinary uses while also appreciating its cultural and agricultural significance.

National Beer Lover’s Day celebrates one of the world’s oldest and most popular beverages. Beer has been brewed for thousands of years, with evidence of its production dating back to ancient Mesopotamia and Egypt. Over time, brewing techniques evolved from small-scale local traditions to large commercial operations, making beer accessible in countless varieties and styles. The day highlights both the cultural significance of beer and the enjoyment it brings, encouraging people to learn more about its history, craftsmanship, and place in communities around the world.

National Buy a Book Day was established in 2012 to encourage book buying as a way to support authors, publishers, and bookstores in an era of declining readership. Held annually on September 7, it calls attention to the cultural and intellectual value of books while urging readers to engage with literature beyond borrowing or digital consumption. The day complements other literary observances like World Book Day, but specifically emphasizes the importance of book ownership as an investment in knowledge and imagination.

National Feel the Love Day encourages people to celebrate the many forms of love in daily life—romantic, familial, platonic, and even the companionship of pets. Observed annually on September 7, it serves as a reminder to pause and express gratitude for the connections that bring meaning and joy. The day emphasizes small acts of kindness, appreciation, and affection that strengthen relationships and uplift communities.

National First Day of Peel Season was introduced in 2021 by Enlightened Beauty to highlight autumn as the ideal time for chemical peels and other exfoliating treatments. With summer sun exposure reduced and cooler months ahead, dermatologists and estheticians view fall as the safest period to refresh skin and repair seasonal damage. The observance underscores the science of skin renewal, encouraging people to prepare their skin for winter while promoting healthier routines in skincare.

National Grandparents Day* (First Sunday after Labor Day) was made official in 1978 when President Jimmy Carter signed legislation following a campaign by Marian McQuade of West Virginia. She envisioned the holiday as a way to honor grandparents, strengthen bonds with grandchildren, and remind younger generations to learn from their elders’ wisdom. The day celebrates family continuity, generational love, and the important role grandparents play in nurturing cultural and family traditions.

National Grandma Moses Day honors the birthday of Anna Mary Robertson “Grandma” Moses (1860–1961), the American folk artist who became famous for her vibrant depictions of rural life. Officially proclaimed in New York in 1960, the day celebrates her remarkable career, which began in her seventies, and her legacy as an artist who showed that creativity and achievement have no age limit. Her paintings remain cultural treasures that capture the simplicity and spirit of early American country life.

National Grateful Patient Day was founded in 2017 by former NFL player Rolf Benirschke, who overcame life-threatening illness to return to professional football. Observed on September 7—the date of his comeback game in 1980—the day encourages patients to express appreciation for doctors, nurses, and caregivers. Many hospitals also use the day to promote “grateful patient programs,” which allow individuals to honor caregivers through philanthropy, creating a culture of gratitude in healthcare.

National New Hampshire Day was introduced in 2017 to celebrate the Granite State’s history, landscapes, and cultural identity. As the ninth state to join the Union, New Hampshire played a central role in shaping early America. Its rugged White Mountains, historic towns, and contributions to politics and industry embody the state’s character. The day serves as a moment of pride for residents and an invitation for others to explore its natural beauty and heritage.

National Neither Snow Nor Rain Day pays tribute to U.S. postal workers, inspired by the phrase inscribed on New York City’s James Farley Post Office: “Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds.” Though never an official USPS motto, the phrase—adapted from the writings of Herodotus—symbolizes the dedication of postal carriers through all conditions. Observed on September 7, it coincides with the 1914 opening of the landmark post office building.

National Pastor’s Spouses Day* (First Sunday in September) was founded in 2022 by the Better Way Apostolic Church to honor the sacrifices of pastors’ spouses. While pastors are often in the public eye, their partners quietly support the ministry, managing families, offering encouragement, and filling roles in the church. This day recognizes their contributions as integral to the spiritual and emotional health of congregations, affirming that the work of ministry is shared.

National Pet Rock Day* (First Sunday in September) celebrates the quirky 1970s fad created by advertising executive Gary Dahl. In 1975, Dahl marketed smooth stones as the “perfect pets”—no feeding, walking, or grooming required—complete with a humorous training manual. The craze sold millions of rocks in just a few months, making it one of the most memorable novelty trends in American pop culture. The day now serves as a nostalgic reminder of creativity, humor, and the power of marketing.

National Salami Day was launched in 2006 by the Salami Appreciation Society in Henrico, Virginia, to honor the centuries-old art of curing and fermenting meat. Salami, derived from the Italian word salare (“to salt”), originated in Southern Europe as a way to preserve pork and beef. Its long shelf life made it a dietary staple for peasants and travelers. Today, salami is enjoyed worldwide in countless varieties, from Genoa and Soppressata to modern artisanal blends, and the day pays tribute to this beloved food.

Superhuman Day began in 2016 as part of Channel 4’s campaign to promote the Rio Paralympic Games. Building on the slogan “We’re the Superhumans,” the day celebrates people with disabilities who achieve extraordinary feats, challenging stereotypes and inspiring wider society to see ability before disability. Today, it has evolved into a broader recognition of resilience, courage, and accomplishment among individuals who overcome obstacles in all areas of life.

World Duchenne Awareness Day is observed every September 7 to highlight Duchenne and Becker muscular dystrophy (DMD/BMD), rare genetic conditions causing progressive muscle degeneration. Founded in 2014 by Elizabeth Vroom and Nicoletta Madia of the World Duchenne Organization, the date reflects the 79 exons in the dystrophin gene. The day raises awareness, funds research, and advocates for improved care for patients. In 2024, the United Nations officially recognized it as an international observance, marking a milestone for rare disease advocacy.
