The International Day of Older Persons, which recognises the contributions and rights of elderly people worldwide, is observed on which date every year?

Introduction / Context:
The International Day of Older Persons is an important United Nations observance that recognises the role of elderly people in society and draws attention to issues such as healthcare, income security, and social inclusion in ageing populations. Many countries use this day to launch policies or awareness campaigns focused on senior citizens. For competitive examinations, questions about the exact date of this observance are common, particularly in general awareness sections related to social sectors and welfare schemes.

Given Data / Assumptions:

• The question refers to the International Day of Older Persons.
• It asks for the date on which it is observed every year.
• Four consecutive dates in October are given: 1, 2, 3, and 4 October.
• We assume the standard UN calendar where this day has a fixed date every year.

Concept / Approach:
The concept tested is knowledge of key social sector related observances. The International Day of Older Persons is celebrated on 1 October each year. The approach is to remember a simple association: the very first day of October is dedicated to older persons, followed by other important observances in early October like Gandhi related days and non violence. By mapping the early days of October with their respective themes, it becomes easy to recall the correct date in an exam setting.

Step-by-Step Solution:
Step 1: Recognise that the question is about the International Day of Older Persons, which focuses on elderly people and ageing.Step 2: Recall that the United Nations observes this day on 1 October every year.Step 3: Look at the options: 1 October, 2 October, 3 October, and 4 October.Step 4: Match your remembered date, 1 October, with option A.Step 5: Choose 1 October as the correct answer.

Verification / Alternative check:
A quick verification method is to remember that 2 October is already reserved for Gandhi Jayanti and the International Day of Non Violence. In contrast, 1 October is associated with older persons and senior citizens. This consecutive order older persons followed by Gandhi and non violence helps you double check that 1 October, not 2 October, is correct for the International Day of Older Persons. Thinking in terms of this simple sequence prevents confusion between adjacent dates.

Why Other Options Are Wrong:
2 October is linked with Mahatma Gandhi and the International Day of Non Violence rather than older persons. 3 October and 4 October do not have any widely recognised UN observances specifically dedicated to older persons and are included as distractors. Selecting any of these alternative dates would indicate confusion between different October observances, which exams are designed to detect.

Common Pitfalls:
Because several international days fall in early October, candidates sometimes mix them up, especially between 1 October and 2 October. Another pitfall is to incorrectly assume that older persons might be celebrated later in the month alongside health or social justice days. To avoid this, memorise a mini calendar of early October: 1 October for older persons, 2 October for Gandhi and non violence, and then other days as needed. Consistent revision of such a mapping makes recall much faster during exams.

Final Answer:
The International Day of Older Persons is observed every year on 1 October.
