International Left Handers Day is observed annually on August 13 to celebrate the uniqueness and differences of the left handers. The day was first observed in the year 1976 by Dean R. Campbell, founder of the Left-handers International, Inc.
International Left Handers Day was created to celebrate certain people’s sinistrality and raise awareness of the advantages and disadvantages of being left-handed in a predominantly right-handed world. It celebrates their uniqueness and differences, who are from seven to ten percent of the world’s population. The day also spread awareness on issues faced by left-handers e.g. the importance of the special needs for left-handed kids, and also the likelihood for left-handers to develop schizophrenia.
