World Braille Day is observed internationally on which date every year to honour the contribution of Louis Braille and promote the rights of persons with visual impairment?

Introduction / Context:
World Braille Day is an important international observance that highlights the significance of Braille as a means of communication and education for people with visual impairment. It honours the contribution of Louis Braille, who developed the Braille system of raised dots, and it raises awareness about the rights of persons who are blind or have low vision. Many general knowledge and current affairs exams ask about the exact date on which World Braille Day is celebrated each year.

Given Data / Assumptions:
- The question asks for the specific date of World Braille Day.
- The options are January 2, January 3, January 4 and January 5.
- The observance is linked to the birth date of Louis Braille.
- International calendars and United Nations observances are the reference context.

Concept / Approach:
World Braille Day is observed on the birth anniversary of Louis Braille, the inventor of the Braille script. Louis Braille was born on 4 January 1809. To honour his work and to emphasise the importance of accessible formats for persons with visual impairment, this date was chosen as World Braille Day. The day is used to discuss inclusive education, accessible information and the role of Braille in ensuring that visually impaired persons enjoy their full human rights and freedoms.

Step-by-Step Solution:
Step 1: Recall that World Braille Day is connected to the birth anniversary of Louis Braille.
Step 2: Remember that Louis Braille was born on 4 January, which is why this date was selected.
Step 3: Look at the options and identify January 4 as the matching date.
Step 4: Eliminate January 2, 3 and 5, as they do not correspond to the accepted international date for this observance.
Step 5: Choose “January 4” with confidence as the correct answer.

Verification / Alternative check:
Learners can verify this by recalling that many news articles, social media posts and government messages on 4 January specifically refer to World Braille Day and to the life of Louis Braille. United Nations related information and disability rights organisations also refer to 4 January as the official date. Since this is a recurring global observance, once a student associates 4 January with World Braille Day, it becomes easy to remember for future exams.

Why Other Options Are Wrong:
- January 2: There is no widely recognised international observance named World Braille Day on this date.
- January 3: This date is close to the correct one, which may confuse candidates, but the official observance is on 4 January, not 3 January.
- January 5: Also incorrect, since major references clearly state that World Braille Day is 4 January.

Common Pitfalls:
Because all options fall early in the same month, candidates may mix up the dates if they rely only on vague memory. Some may think of 3 January or 5 January simply because they remember the observance as being in the first week of January. To avoid such confusion, learners should link the date strongly with the person. Remember: Louis Braille was born on 4 January, and the day chosen to celebrate his legacy is 4 January, World Braille Day. Creating a small mental association such as “Braille and four raised dots point to 4 January” may also help some students remember the correct date.

Final Answer:
World Braille Day is observed every year on January 4.
