International Left Handers Day is an international day observed annually on August 13 to celebrate the uniqueness and differences of left-handed individuals. The day was first observed in 1976 by Dean R. Campbell, founder of Lefthanders International, Inc.[1]

International Lefthanders Day was created to celebrate sinistrality and raise awareness of the advantages and disadvantages of being left-handed in a predominantly right-handed world. It celebrates left-handed people’s uniqueness and differences, a subset of humanity comprising seven to ten percent of the world's population.[2] The day also spreads awareness on issues faced by left-handers, e.g. the importance of the special needs for left-handed children, and the likelihood for left-handers to develop schizophrenia.[3][4]

Several media outlets and commercial associations have made one-off posts and compilations of accomplished left-handed people in recognition of the holiday.[5][6]
