August 25, 2026, is the 237th day of the year, with 128 days remaining, and it falls on a Tuesday — in the thirty-fifth week of the year.
With 8 national and international days on the calendar, August 25 punches well above its count. The National Park Service celebrates its 110th anniversary today — 423 protected sites, 85 million acres, and one of America’s most consequential conservation decisions. Milad an-Nabi falls on August 25 this year, bringing the Prophet Muhammad’s birthday to 1.8 billion Muslims worldwide. Instant Ramen Day marks 68 years since Momofuku Ando’s August 25, 1958 invention at Nissin. And the banana split turns 122, still unapologetically topped with three sauces.

National & International Days on August 25
Whether you’re visiting a national park, eating a banana split and a whiskey sour, making instant ramen, observing Milad an-Nabi, kissing and making up, shopping secondhand, or simply starting Be Kind to Humankind Week with one deliberate act of consideration, here’s the story behind each of these August 25 celebrations.
National Banana Split Day
National Banana Split Day commemorates the invention of the iconic dessert by David Evans Strickler, a pharmacist’s apprentice in Latrobe, Pennsylvania, in 1904. Working at Tassel Pharmacy’s soda fountain, Strickler sliced a banana lengthwise, added three scoops of ice cream, and topped it with syrups, whipped cream, nuts, and a cherry. The creation quickly became popular, spreading beyond Pennsylvania and becoming a staple of American soda fountains. Latrobe proudly celebrates its legacy with an annual festival, and the U.S. Postal Service honored the banana split with a commemorative stamp in 2016.
National Kiss and Make Up Day
National Kiss and Make Up Day encourages reconciliation and forgiveness after disagreements. The phrase “kiss and make up” dates back to at least the 16th century as a symbolic way to resolve disputes. In modern times, Jacqueline Milton established the observance to remind people to let go of resentment and take steps toward repairing broken relationships, promoting harmony in both personal and professional life.
National Park Service Founders Day
National Park Service Founders Day marks August 25, 1916, when President Woodrow Wilson signed the Organic Act, creating the National Park Service. Tasked with protecting natural and cultural treasures “unimpaired for the enjoyment of future generations,” the NPS today manages more than 400 sites across all U.S. states and territories, encompassing over 84 million acres. The day celebrates both the agency’s founding and its ongoing role in conservation, education, and stewardship of America’s landscapes and heritage.
National Secondhand Wardrobe Day
National Secondhand Wardrobe Day promotes sustainable fashion choices by encouraging people to buy pre-owned clothing. Long before thrift stores, garments were valued and reused, passed down through families or altered into new items. Charities like Goodwill and the Salvation Army formalized thrift shopping in the late 19th century, turning donated clothing into funds for social programs. Today, secondhand fashion has regained popularity as consumers seek eco-friendly, affordable, and unique alternatives to fast fashion.
National Whiskey Sour Day
National Whiskey Sour Day honors the classic cocktail that pairs whiskey with citrus and sugar in a refreshing balance. The sour cocktail family traces back to the 1700s, when sailors mixed spirits with lime juice to prevent scurvy. The whiskey sour was formalized in Jerry Thomas’s The Bartender’s Guide (1862), with early mentions appearing in U.S. newspapers by 1870. Its enduring appeal lies in its simplicity and versatility, making it a staple of cocktail culture for more than 150 years.
