World Suicide Prevention Day (WSPD), an awareness day focused on preventing suicide worldwide, is observed every year on which of the following dates?

Introduction / Context:
World Suicide Prevention Day (WSPD) is a global awareness day that aims to focus attention on suicide prevention, reduce stigma, and encourage support for people who may be at risk. Mental health awareness has become a key theme in many exams, and this date is frequently tested as part of the important-days section.

Given Data / Assumptions:

• The observance is World Suicide Prevention Day (WSPD).
• The options are 1 September, 7 September, 9 September, and 10 September.
• We must determine the exact date each year on which this day is observed.

Concept / Approach:
The International Association for Suicide Prevention (IASP), together with the World Health Organization, observes World Suicide Prevention Day on 10 September each year. The other dates listed are in the same month and are chosen to confuse candidates who only remember that the observance is sometime in early September. The correct approach is to fix the specific date “10 September” in memory.

Step-by-Step Solution:
Step 1: Identify the observance: World Suicide Prevention Day, related to mental health and suicide prevention. Step 2: Recall that internationally, WSPD is observed on 10 September every year. Step 3: Compare this with the options: 1 September, 7 September, 9 September, and 10 September. Step 4: Confirm that 10 September matches the official date used by IASP and WHO. Step 5: Recognise that the other dates, although close, are not used for this observance. Step 6: Select 10 September as the correct answer.

Verification / Alternative check:
This date can be verified by checking WHO campaigns, IASP information pages, and news articles that cover World Suicide Prevention Day events. They consistently refer to 10 September, often highlighting annual themes and community activities held on that day.

Why Other Options Are Wrong:
1 September: Not recognised internationally as WSPD and used only as a distractor.
7 September: Another early September date without official WSPD status.
9 September: Very close to the correct date but still wrong, included to trap those who are unsure.

Common Pitfalls:
Candidates may confuse WSPD with other health-related observances in September or may vaguely remember that it is “in early September” without the exact date. The best strategy is to pair “suicide prevention” firmly with “10 September” and to recall that it is coordinated by the International Association for Suicide Prevention with support from the World Health Organization.

Final Answer:
Therefore, World Suicide Prevention Day is observed every year on 10 September.
