Common mistakes
| Mistake | Why it happens | Fix |
|---|---|---|
| All months have 30 days | Forgetting 31-day months | Jan, Mar, May, Jul, Aug, Oct, Dec have 31 |
| February always 28 | Leap year | Leap year Feb = 29 |
| December before November | Reverse order error | Use month rhyme or knuckle trick |
| Confusing festival date with month length | Separate facts | Know which month festival falls in |
Quick check
- Days in February (non-leap)?
- Month after July?

- Stretch: How many days from 1 March to 1 June in a non-leap year? (31+30+31 = 92 days)
