The International Day of Sign Languages is observed annually on which date?

Introduction / Context:
The International Day of Sign Languages is observed to raise awareness about the importance of sign languages and to promote the human rights of deaf people worldwide. It emphasizes that sign languages are full, natural languages that must be respected and supported. This day is observed every year on 23 September. General knowledge exams increasingly include such observances to test awareness of inclusivity, disability rights and language diversity.

Given Data / Assumptions:
- The observance is the International Day of Sign Languages.
- It is an annual UN recognized day.
- The options cluster around dates in late September to test accurate recall of the exact day.

Concept / Approach:
The key concept is to associate sign languages with 23 September. One practical memory tip is to remember that this date marks the founding of the World Federation of the Deaf, which strongly supports the observance. You can imagine “two” and “three” in 23 as representing connection between two parties through three components: hands, facial expressions and body language, symbolizing sign communication, as a playful mnemonic.

Step-by-Step Solution:
Step 1: Read the name “International Day of Sign Languages” and identify it as a UN observance related to deaf communities. Step 2: Recall that the United Nations chose 23 September as the annual date for this observance. Step 3: Look through the choices and find 23 September among them. Step 4: Note that neighbouring dates like 24, 25 and 26 September are often used as distractors and do not match the official UN resolution. Step 5: Select 23 September as the correct answer once you have ruled out the other options.

Verification / Alternative check:
As an alternative, recall that the International Week of the Deaf often centres around 23 September, reinforcing that this date has special significance. News articles and awareness campaigns from deaf organizations are frequently scheduled around 23 September, which further confirms the link. No similar pattern of sign language related coverage exists for 21, 24, 25 or 26 September, helping you validate your choice.

Why Other Options Are Wrong:
24 September: Not the designated UN date for this observance, though it may fall within celebrations around the International Week of the Deaf.
25 September: Used as a distractor date and not specified in the UN resolution for the International Day of Sign Languages.
26 September: Associated with other events in some contexts, but not this particular observance.
21 September: Known for the International Day of Peace, which focuses on conflict resolution and global peace, not sign languages.

Common Pitfalls:
Because several UN observances occur in September, candidates may confuse the International Day of Peace, International Literacy Day and the International Day of Sign Languages. Another pitfall is to assume that any date within the International Week of the Deaf is equally correct, whereas the exam requires the specific official date of 23 September. To avoid these mistakes, explicitly associate “sign languages” and “deaf rights” with 23 September in your revision notes.

Final Answer:
Correct option: 23 September
