Common Mistakes to Avoid
| Mistake | Why Students Make It | Correct Approach |
|---|---|---|
| Confusing Jayanti with Diwas | Assume both are holidays | Jayanti = birth (celebratory), Diwas = observance; only Jayanti of Gandhi & Ambedkar are public holidays |
| Switching 16 Sep & 16 Nov | Similar numbers | Ozone-16-Sep (O-S same shape), Tolerance-16-Nov |
| Thinking 31 May is “No-Tobacco” | Full-moon rule forgotten | WHO fixes “World No-Tobacco Day” as 31 May every year (no full-moon link) |
| Believing 2nd Saturday is always Blood Donor Day | Shift-II exams ask movable date | Read “2nd Saturday of June” not fixed 14 Jun |
