About International Left Handers Day
International Left Handers Day has been celebrated on August 13th since 1976. About 10% of the world's population is left-handed — a proportion that has stayed remarkably stable throughout history. The day celebrates lefty pride and highlights everyday challenges, from scissors to spiral notebooks, in a world designed for the right-handed majority.

Roughly one in ten people is left-handed — a ratio that has stayed remarkably stable across cultures and throughout recorded history, suggesting evolution keeps lefties around on purpose. Handedness emerges before birth: ultrasound studies show most fetuses already favor one thumb in the womb.
A Left-Handed History
History wasn't kind to lefties: the Latin word for left, sinister, says it all, and generations of schoolchildren were forced to write right-handed. Yet the left-handed roster is remarkable — Leonardo da Vinci wrote in mirror script, and modern lefties include Paul McCartney, Bill Gates, Oprah Winfrey and four of the last eight U.S. presidents.
The Southpaw Advantage
In interactive sports, left-handers punch far above their weight: they are overrepresented among elite fencers, boxers and tennis players, because opponents train mostly against righties. Left-Handers Day, celebrated since 1976, is marked with 'lefty zones' where right-handers try scissors, can openers and writing left-handed — and finally understand.
