Months of the year

You learn how many days each month has, with your knuckles as a guide.

How to work it out

  1. Knuckles represent 31-day months; valleys represent 30-day months.
  2. Remember February is 28 days (29 in a leap year).

A worked example

April

  1. Count on your knuckles: January, February, March, April.
  2. April falls in a dip.
  3. April has 30 days.
More examples

August

  1. Count on your knuckles up to July, on the last knuckle.
  2. Start again at the first knuckle: August.
  3. August has 31 days.

February

  1. February falls in the first dip, but is the exception.
  2. February has 28 days, and 29 in a leap year.

Try it yourself

  1. Which month of the year is this?

  2. How many days are in this month?

Watch out

  • You go to a dip after July: August gets 30 days.

    After the last knuckle (July) you start again at the first knuckle. July and August both have 31 days.

  • You give February 30 days because it falls in a dip.

    February is the only exception: 28 days, and 29 in a leap year.

Tips

  • July and August both have 31 days.

Exceptions

  • February has 28 days, and 29 in a leap year.

Why it works

Months have 30 or 31 days, and that is hard to remember. Your knuckles show it: a knuckle sticks up, 31 days; a dip goes down, 30 days. Only February is different: it has 28 days.
