The Knuckle Calendar for kids: the whole trick

Somebody names any month of the year. You look at your knuckles for a second and tell them how many days it has. You never get it wrong, even for February. It's a level 1 apprentice trick for ages 6 to 10 (grades 1stโ€“4th), takes 5 minutes to learn, and needs nothing but your hands. Flick, the shop's rabbit, reads every step aloud with a picture, so a child can follow it alone.

The secret

Make two fists and name the months along your knuckles and the dips between them. A month on a knuckle has 31 days, a month in a dip has 30, and February, in the first dip, has 28 or 29.

What you need

Nothing at all: this one is done with your hands.

How to do it

  1. Make two fists and put them side by side, knuckles up.
  2. Practise first: say January on the first knuckle, February in the dip after it.
  3. Keep going along the knuckles and dips. July lands on the last knuckle of your first fist.
  4. Knuckle months have 31 days. Dip months have 30, and February has 28.
  5. Now ask somebody to name any month, tap along your knuckles, and say its days!

Magic words to say

โ€œMy knuckles are a calendar. I had them made specially. Name any month, any month at all, and they'll tell me how long it is.โ€

Pro tips

  • Tap quietly with one finger, or do it in your head once you know it.
  • For February, say "28, and 29 in a leap year". It makes you sound like an expert.
  • After the trick, show them how. This is a secret worth giving away.

If something goes wrong

If you lose your place, start again from January and tap faster. Say "the calendar needs warming up".

Safety notes

  • No fire, no flames and nothing sharp in a child's hand anywhere in the Magic Shop. Nothing ever goes in a mouth, a nose or an ear.

Why it works

The months with 31 days are January, March, May, July, August, October and December. On two fists in a row they fall exactly on the knuckles, because a month on a knuckle and a month in a dip take turns, with July and August both on knuckles where the fists meet.

What kind of trick is this?

๐Ÿ”ฎ Prediction. You knew all along, or you read their mind. Almost every trick ever invented is one of eight kinds, and knowing which one you're watching is how magicians work out how a new trick is done.

The skill it teaches: Patter: what you say. A trick is a story, not a thing that happens. Perform it and it counts towards the Mind Reader badge.
