The day is observed every year to celebrate the uniqueness and differences of the left-handers and raise awareness of the advantages and disadvantages of being left-handed in a predominantly right-handed world.
Left-handers are likely to have better verbal skills than their right-handed counterparts, according to a 2019 study by Oxford University.
The day was first observed in 1976 by Dean R Campbell, the founder of Lefthanders International Inc.
