Answer: January 4
Notes: World Braille Day is observed every year on 4 January. The day marks the birth anniversary of Louis Braille, a French educator born in 1809. He invented Braille in 1824, a code using six raised dots that allows visually impaired people to read with their fingertips. Braille is used globally in many languages for reading, writing, solving math problems, scientific equations, learning music, and daily activities like shopping. In New Delhi, the National Federation of the Blind organized a function to commemorate the day and launched a campaign called More Braille More Empowerment to promote equality and dignity for visually impaired people.
