Effect

The assistant tears a monthly sheet off the calendar pad. You turn your back on him. He is told to mark off one day in each week. You now ask, “How many Sundays are checked?” “How many Mondays?” “How many Tuesdays?” etc. Immediately after this questioning you name a number. The man with the calendar sheet adds up the dates he's marked and finds that you have called the total correctly!

How it is done

The method, 1 drawing and all it needs, inside the library.
