The Magical Week

Trick Effect & Routine:

You give your friend a monthly calendar and have him or her flip the pages to any month. After you turn your back, have your friend circle three consecutive days on the calendar — any days at all, as long as they are consecutive.

After a question and a mental calculation, you reveal all three dates!

Amazing mindreading that you can do!

Preparation:

What you need:

A monthly calendar (where all of the dates for one month are on each page).
A pen or pencil.
A calculator, if you want to be really safe.

Method:

Give your friend the calendar and turn your back. Instruct him or her to flip to any page and to circle three consecutive dates on the calendar. These can be days he likes (vacation days, holidays, etc.) or whatever!

Instruct your friend to mentally add the three numbers (dates) and give you the total. Then, you mentally divide the total given to you by 3. This will be the second date of the three your friend circled. Since you know the middle date, subtract 1 for the first date and add 1 for the third date!

Presentation Tip:

Instead of just blurting out the three dates, "You picked the 23rd, 24th, and 25th!", ask your friend if those dates have any real meaning to him or her.

"Yes", your friend says, "It's the day I met my in-laws!"

"Ah!', you say, "That would be the 23rd, 24th, and 25th!"

See the difference?
