Find the odd commemorative date (India): Select the date that is not a national holiday across India, unlike the others listed.

Introduction / Context:Calendar-classification items often use national holidays vs observances. In India, certain dates are official nationwide holidays; others are commemorations without universal holiday status.

Given Data / Assumptions:

• 15th August: Independence Day (national holiday).
• 26th January: Republic Day (national holiday).
• 2nd October: Gandhi Jayanti (national holiday).
• 14th November: Children’s Day (observed; not universally a nationwide public holiday).

Concept / Approach:Identify which dates are legally recognized as national holidays vs cultural/educational observances.

Step-by-Step Solution:

Verification / Alternative check:Cross-check common school calendars: 14 Nov often has events but not mandatory closure nationwide, unlike the other three dates.

Why Other Options Are Wrong:They are official national holidays.

Common Pitfalls:Equating widespread observance with legal holiday status.

Final Answer:14th November
