Pocket Dreams (Gimmicks and Online Instructions) by Mago Larry - Trick

Do you like effects whereby the spectator has free choice of their actions, and you are then able to prove that you knew the outcome beforehand? Well, Pocket Dreams is right up your alley!

The spectator is shown a pocket calendar containing all the dates of the year. The dates have information written on them, such as a fact, event, city, name, card, etc. The spectator freely chooses any date. Astonishingly, the information located on that date precisely matches the prediction the magician had written previously!

You'll love performing this one.
