October 10: Holidays, Historical Events, Famous Birthdays & Zodiac Sign

About October 10

October 10 is known worldwide as Double Ten Day, commemorating the 1911 Wuchang Uprising that erupted the day after a bomb accidentally exploded, pushing revolutionaries to act before they were arrested. That revolt toppled the Qing Dynasty and gave birth to the Republic of China in 1912—a turning point still celebrated with flag-raising ceremonies and parades in Taiwan and among Chinese communities globally.

The date brims with other declarations of sovereignty. Fiji raised its own flag for the first time on this day in 1970, ending nearly a century of British colonial rule. Vietnam marks the liberation of its capital, while Sint Maarten honors its constitution and Curaçao celebrates autonomy—both milestones following the 2010 dissolution of the Netherlands Antilles. Sri Lanka, meanwhile, observes Army Day, and Poland plants trees for Arbor Day.

October 10 has also witnessed pivotal moments in exploration and science. William Lassell spotted Triton, Neptune's largest moon, in 1846, just weeks after the planet itself was discovered. In 1913, President Woodrow Wilson triggered an explosion that flooded the Gamboa Dike, completing the Panama Canal's massive construction. And in 1964, the Tokyo Olympics opening ceremony became the first broadcast live via satellite, connecting audiences across continents in real time.
