World Radio Day, proclaimed by UNESCO to celebrate radio as a medium, is observed on which date each year?

Introduction / Context:
World Radio Day is a global observance proclaimed by UNESCO to celebrate radio as a powerful and affordable medium for communication, information, and emergency broadcasting. Even in the age of the internet, radio remains crucial for reaching remote and under connected areas. For competitive exams, this date is commonly asked in media, communication, and general awareness sections, especially when international observance days are tested.

Given Data / Assumptions:

• The question concerns World Radio Day.
• It mentions that the day celebrates radio as a medium.
• All four options are dates in February.
• We assume the candidate has revised the list of important UNESCO and United Nations days.

Concept / Approach:
World Radio Day is observed every year on 13 February. The date was chosen to coincide with the anniversary of the establishment of United Nations Radio. The conceptual approach involves recognising that February has several observances, but 13 February is uniquely associated with radio. By remembering that radio communication is celebrated just before the widely known Valentine Day on 14 February, students can create a simple mental anchor for this date.

Step-by-Step Solution:
Step 1: Identify that the observance in question is World Radio Day. Step 2: Recall that UNESCO declared 13 February as the official date to celebrate radio. Step 3: Keep in mind that this date marks the founding of United Nations Radio, which provides a historical basis. Step 4: Compare this recalled date with the options given, namely 13, 14, 11, and 15 February. Step 5: Choose option A, 13 February, as it correctly matches World Radio Day.

Verification / Alternative check:
Verification can be done through UNESCO information pages, lists of UN observance days, and GK compendiums that cover media related days. Every year, many broadcasters and community radio stations run special programmes on 13 February specifically labelled as World Radio Day. Seeing this date repeatedly in multiple credible sources reinforces the correct association in the minds of exam aspirants.

Why Other Options Are Wrong:
Option B, 14 February, is widely known as Valentine Day and is not associated with World Radio Day.
Option C, 11 February, is not the UNESCO proclaimed date for this observance.
Option D, 15 February, is also not linked with World Radio Day in standard GK references.

Common Pitfalls:
Candidates sometimes confuse World Radio Day with other communication related days or place it on 14 February because they focus on mid February without checking the exact date. Another mistake is to ignore media and communication observances during revision, leading to uncertainty among nearby dates. To avoid this, students can remember a simple pattern where World Radio Day on 13 February is followed by Valentine Day on 14 February, forming a clear chronological pair in the month.

Final Answer:
World Radio Day, proclaimed by UNESCO, is observed each year on 13 February.
