How To: Use your knuckles to remember days in a month

Use your knuckles to remember days in a month

Keep forgetting how many days are in each month? Here is a handy trick you can bust out anytime you need to remember if this is and even or and odd month. After you master using your hands, try using your feet!

Our ancestors just dragged them along the ground, but you can put your knuckles to good use with this neat trick.

You Will Need

* One or two hands
* One or two feet (optional)

Step 1: Position hands

Ball your hands into fists and hold them front of you.

Step 2: Begin on the left

Count the months on your knuckles and the grooves in between, starting with January on your leftmost knuckle, which is your left pinky.

Step 3: Count

Don't count your thumb's knuckles or any space between your hands. Each of the seven months that land on a knuckle will be months with 31 days. The five months that fall on the grooves all have 30 days.

Step 4: Remember February

Remember the one exception – February – that falls on a groove. It has 28 days, or 29 in a leap year.

This trick works just as well using your feet instead of your hands.

Step 5: Try one hand

Try this trick with one hand, too. When you get to the last knuckle, loop around and continue counting on the first knuckle.

Julius Caesar, on the advice of the Greek astronomer Sosigenes, invented the leap year in the year 46 B.C.E.
