International Left-Handers Day

International Left-Handers Day is a true celebration for those who view the world from a left-handed perspective. Scientists estimate that around 825 million left-handed people live on the planet. The highest percentage is found in Papua New Guinea, where nearly a quarter of the population is left-handed. In the United States and the United Kingdom, that number is approximately 10%.

History

The day was first observed in 1976 at the initiative of Dean R. Campbell, founder of Lefthanders International, Inc. In 1990, a dedicated left-handed club was created to address social and practical challenges, provide support, and conduct research. Members of the club also work to find tools and products that make everyday life easier for left-handers.

International Left-Handers Day is recognized worldwide, but it receives special attention in the United Kingdom. The country hosts themed parties, sports events, local festivals, and other activities.

The holiday’s goal is to raise awareness that being left-handed is entirely normal and natural.
