August 13 is designated International Left-Handers Day by Lefthanders International. It was first observed on the 13th of August, in the year 1976. As the name suggests, it is meant to promote awareness of the inconveniences faced by left-handers in a predominantly right-handed world. It celebrates their uniqueness and differences, who are from seven to ten percent of the world's population. Hundreds of millions of left-handed people in today's society have to adapt to use right handed tools and objects.
There’s also a more serious side to the day, which spreads awareness about the special needs of left-handed kids. Also, left-handed people may be more likely to develop schizophrenia because of their enhanced creativity and imagination.
While it had been observed on Aug. 13 of each year by many left-handers since 1976, Left-handers Day was declared by the Left-Hander's Day Club on August 13, 1997. It was made to annually celebrate certain people's sinistrality and raise awareness of the advantages and disadvantages of being left-handed.
