January 11th: National & International Days, Celebrations and Observances
January 11 recognizes the fight against human trafficking, bringing needed attention to this ongoing crisis. The same date sees people worldwide pause to celebrate International Thank You Day.
Winter weather makes this perfect timing for a hot toddy. Many also raise a glass of milk, marking National Milk Day with this dietary staple.
People mark this date by learning new ways to reach out. Some tap out their first Morse code messages. Down the hall or across town, others pick up pen and paper to write personal notes.
This quiet practice of letter writing fills mailboxes during Universal Letter Writing Week. Each message, whether tapped or written, creates a moment of personal connection.
January 11 marks National Human Trafficking Awareness Day and International Thank You Day. The date also includes National Milk Day, Learn Your Name in Morse Code Day, and National Hot Toddy Day. These observances occur during National Pizza Week and Universal Letter Writing Week.

Did You Know? January 11th Facts and Historical Events
On January 11th, science and conservation reached notable turning points.
- A chilly night in Bath, 1787: William Herschel aimed his telescope toward Uranus. His observations revealed two moons - now called Titania and Oberon. These frozen satellites drift in distant orbit, spanning roughly 1,576 and 1,522 kilometers.
- The start of 1908 brought critical change to Arizona's landscape. Mining companies had targeted the Grand Canyon until President Theodore Roosevelt took action. His designation protected 808,120 acres as a National Monument, blocking commercial exploitation of this vast gorge.
- By 1935, most considered trans-Pacific solo flights impossible. Amelia Earhart proved them wrong. She piloted her Lockheed Vega across 2,408 miles of open ocean, keeping steady at 8,000 feet. When she landed in Oakland after 18 hours and 15 minutes, she had opened new possibilities for long-distance flight.
January 11th - Notable Birthdays
History remembers January 11th as a birthday worth noting.
- Few paid attention to Aldo Leopold's birth in small-town Iowa, 1887. He spent countless hours watching nature, recording observations that grew into his life's work, "A Sand County Almanac." While others talked, Leopold acted - establishing what would become America's first protected wilderness. The Wilderness Society grew from his vision, and today's conservationists still build on his practical "land ethic" ideas.
- Alice Paul wasn't your typical academic. Armed with a sociology PhD in the early 1900s, she engineered protests that finally won women's voting rights in the 19th Amendment. Perhaps her greatest legacy? Writing the Equal Rights Amendment. The peaceful resistance methods she developed still work for activists today.
- Since the 1980s, Kailash Satyarthi (b. 1954) has waged a personal war against child exploitation. His relentless efforts have pulled 80,000 children from forced labor. His organization GoodWeave keeps proving something vital: businesses thrive when they protect their workers and the environment.
- Matt Mullenweg probably never imagined WordPress would grow so big. Created in his college days (b. 1984), his publishing tool now runs more than 4 in 10 websites worldwide. Beyond giving millions a voice online, WordPress helped normalize working from home - cutting daily commutes and making information freely available to anyone with internet access.
