International Lefthanders Day is observed worldwide on August 13 each year. Established in 1976 by Lefthanders International, this day highlights the challenges faced by the approximately seven to ten percent of the global population who are left-handed. It promotes public awareness of the difficulties that lefthanders encounter in a predominantly right-handed world, including the need to adapt to tools and objects designed for right-handed users. Historically, left-handed individuals were often encouraged to switch to right-handedness, a practice that continues in some countries, such as China, where left-handed children are still required to write with their right hand. The celebration allows left-handed people to embrace their uniqueness while providing an opportunity for right-handed individuals to understand the advantages and disadvantages of being left-handed.
