The International Day of United Nations Peacekeepers is observed on which date each year to honour UN peacekeeping personnel?

Introduction / Context:
The International Day of United Nations Peacekeepers is dedicated to honouring the service and sacrifice of men and women who work in UN peacekeeping missions around the world. It also pays tribute to those who have lost their lives under the UN flag. This question asks for the specific date on which this day is observed every year, a key fact in international organisations and current affairs general knowledge.

Given Data / Assumptions:

• The observance is called the International Day of United Nations Peacekeepers.
• It is held annually on a fixed calendar date.
• The options include several consecutive dates in late May and one date in early June.
• Only one of these dates corresponds to the official UN observance for peacekeepers.

Concept / Approach:
The United Nations selected a specific date in May to mark this observance. The chosen date remembers the first UN peacekeeping mission that started operations and symbolises the long history of peacekeeping efforts. For exam purposes, students are expected to memorise that this day is commemorated on 29 May every year. The options are close to each other to test detailed recall rather than approximate memory.

Step-by-Step Solution:
Step 1: Remember that the International Day of UN Peacekeepers is associated with the end of May.Step 2: From United Nations calendars and general knowledge guides, recall that 29 May is the exact date chosen for this observance.Step 3: Scan the options and identify 29 May as option B.Step 4: Confirm mentally that each year UN headquarters and field missions hold ceremonies specifically on 29 May.Step 5: Mark 29 May as the correct answer.

Verification / Alternative check:
Every year, official UN announcements, social media posts, and ceremonies that honour fallen peacekeepers are anchored on 29 May. They often include wreath laying, medal ceremonies, and public statements by UN leaders. No similar consistent worldwide observance is associated with 28 May, 30 May, 31 May, or 1 June for this particular purpose, which confirms that 29 May is the correct date for the International Day of United Nations Peacekeepers.

Why Other Options Are Wrong:
28 May: This date is one day earlier than the official observance and is used only as a close distractor.

30 May: This is one day later and has no established link as the designated peacekeepers remembrance day.

31 May: This date is famous in health contexts as World No Tobacco Day, not as the day for UN peacekeepers.

1 June: This is in the next month and is not recorded as the official date for this UN observance.

Common Pitfalls:
Students sometimes confuse 29 May with 31 May because both are important international days occurring close together. Another mistake is to remember only that the observance happens in late May without fixing the precise date. Creating a small mental timeline where 29 May is linked with blue UN helmets and 31 May with anti tobacco campaigns can help separate these two important days and improve accuracy.

Final Answer:
29 May
