September 9: Holidays, Historical Events, Famous Birthdays & Zodiac Sign

About September 9

September 9 has a peculiar habit of marking journeys that changed the map. Vasco da Gama's fleet returned triumphantly to Lisbon in 1499, concluding a grueling two-year expedition around the Cape of Good Hope to India. Three years earlier, Christopher Columbus had departed Cadiz with seventeen ships and 1,200 men for his second transatlantic voyage. And in 1588, Thomas Cavendish navigated the Desire into Plymouth Harbor, finishing what historians credit as the first intentionally planned voyage around the world. Not all of the day's milestones were nautical, but many involved redrawing boundaries: the Continental Congress formally adopted the name "United States" for its union in 1776, and in 1791, the new American capital was officially named Washington, D.C., in honor of the sitting president.

Modern September 9s have been equally consequential. California became the thirty-first U.S. state in 1850, a admission hastened by the Gold Rush. In 1956, an estimated 60 million Americans tuned in as Elvis Presley made his first appearance on The Ed Sullivan Show, cementing a cultural revolution. Queen Elizabeth II surpassed her great-great-grandmother Victoria in 2015 to become the longest-reigning British monarch. And in the realm of technology, two events stand out: George Stibitz's 1940 demonstration of the first remote computer operation, and the 2014 release of U2's Songs of Innocence, which landed automatically in the music libraries of over half a billion iTunes customers—whether they wanted it or not.

For a day that also commemorates solemn moments—the Stono Rebellion of 1739, the beginning of the Attica prison riot in 1971, and Slovakia's remembrance of Holocaust victims—September 9 carries a surprisingly optimistic zodiac sign. Virgo, the analytical and service-oriented sign, seems fitting for a date that gave the world Luigi Galvani, the Italian physicist who made frogs' legs twitch with electricity, and Dennis Ritchie, the Bell Labs programmer who created the C programming language. Both men, born on this day in 1737 and 1941 respectively, quietly built foundations that billions would later rely upon.
