September 14: Holidays, Historical Events, Famous Birthdays & Zodiac Sign
On September 14, 2015, scientists detected gravitational waves for the first time, confirming Einstein's century-old theory of spacetime ripples.
About September 14
September 14 is a day of quiet revolutions. In 1752, Britain and its colonies went to sleep on September 2 and woke up on September 14, adopting the Gregorian calendar by skipping eleven days. Citizens reportedly rioted, demanding their missing days back. Centuries later, the date delivered another leap for human knowledge: in 2015, the LIGO and Virgo collaborations observed gravitational waves for the first time, confirming a prediction Albert Einstein made a century earlier.
The day also echoes with national milestones. In 1814, Francis Scott Key witnessed the bombardment of Fort McHenry and penned a poem that became the lyrics of The Star-Spangled Banner. In 1960, OPEC was founded, reshaping global energy politics. And in 1984, Joe Kittinger became the first person to solo a gas balloon across the Atlantic, chasing the horizon with the same spirit that defines the day's Virgo energy.
