Easy Ways to Remember 30- and 31-Day Months
The Month Rhyme
A traditional rhyme gives a quick way to remember the shorter months:
Thirty days hath September,
April, June and November.
All the rest have thirty-one,
except February, with twenty-eight — or twenty-nine in a leap year.
April, June and November.
All the rest have thirty-one,
except February, with twenty-eight — or twenty-nine in a leap year.
So the four months with 30 days are April, June, September and November. February has 28 or 29; the remaining months have 31.
The Knuckle Method
Make a fist and count the months across your knuckles and the dips between them. A knuckle means 31 days. A dip means 30 days, except February, which has 28 or 29.
Knuckle: 31 days
Dip: 30 days (February is the exception)
Why July and August both have 31 days: July finishes on the last knuckle of the first pass. Restart the count for August on the first knuckle, so August is also a 31-day month.
