Twelve months — the basic chunks of the year.
Quick check
Which month has 28 days (or 29 in a leap year)?
Days in each month
- 31 days — Jan, Mar, May, Jul, Aug, Oct, Dec
- 30 days — Apr, Jun, Sep, Nov
- 28 days (29 in a leap year) — Feb
- Rhyme: thirty days hath September, April, June, and November...
Knuckle trick: make a fist. Knuckles = 31-day months, dips between them = 30-day months (Feb being the exception). Run Jan→Dec across both fists.
Your turn
Does August have 30 or 31 days?
Knuckle trick: count months across knuckles and dips. Knuckles = 31 days, dips = 30 (or 28/29 for Feb).
