Is there someone who knows a formula to fill in a birthday book with the cards of a mem deck but in such a way that if the card is named, you know de date AND if they name a date, that you know the card. Thus a system that workd both ways and that can be applied with every mem deck.
Thanks in advance.

I don't know if the first item is possible  there are roughly 365 days to cover, but only 52 cards, so when someone names a card, that card is going to land on one of seven dates is it not? I think you would need a second piece of information to tie with the card being named to make it unique from it's similar dates.
Thanks, Jason

Here is a discussion on the Birthday Calendar, including a printout of the calendar for the Aronson stack.
http://www.themagiccafe.com/forums/viewt......orum=205 Jason, a card can land on one of up to 31 DATES.

If you did it in reverse, as you are asking, there would be multiple dates that could be associated.

It is of course not a trick but maybe it can be amusing when during your performance someone freely names or pick a card and you can say: "Wow, how did you know that precise this day it is this card's birthday ?" and you throw the birthdaybook on the table. Sort of making use of an opportunity that occurs at the moment.

Now that's just silly.

While there will be several dates in the calendar with the same card, that doesn't stop you from performing the proposed effect. We'll use Simon's system as an example. Simon uses the common number for each month: Jan = 1, Feb =2, and so on. Then he adds the date number. So if someone's birthday is Jan (1) First (1) the card at the date of Jan, 1 will be the King of Clubs or Stack Number 2 in Simon's stack.
Given that, let's say the spectator chooses the Seven of Diamonds and you want to name it's "Birthday." The Seven of Diamonds is stack number 15. So we just need to find a month and date number which adds up to 15. Let's try January to make it easy. January is 1, so it's almost automatic to see that January 14th will have that card. We open the book and display it. The fact that the same card appears at many other locations in the book is irrelevant. (Should someone notice that the same card appears at another date, you point out that it has to, because there are 365 days and only 52 Cards.) Which opens up another possibility: After you say that the card's birthday is January 14 and show that, you can say that it's a lucky card and also has a birthday on April 11... and display that. (You don't want to do February after January because that will betray that the cards birthday each month moves up by one.)Quickly do as many as you wish, going faster and faster so it doesn't lag. The calculations are easier for lower stack numbers, but even the higher number are not difficult. Try it. Remember this: All of the cards with stack numbers higher than 11 will appear once on every month in the book. Numbers lower than 11 will appear, but the number of times they appear will be one less that the stack number itself. (The Three of Hearts appears six times because it's stack number is 7.)

Thank you for the answers.
In my "formula" to calculate the date, I made two exeptions who ate very easy to remember. The first of jan is the number 1 of my mem deck (I made my own) and the 31 december is the last card of my mem deck. With my "formula" (and others likewise I presume) the numbers 1 and 52 are never reached. So I have at least two cards who are unique and would otherwise never appear on the calendar.

I didn't mean to misquote Simon. Possibly I have confused Mike Close's System with his. I'll have to do a little research. What I use myself is a Birthday book with the cards written in for each date, not Simon's all on one card where you could see the same card appearing in diagonals on the card. For this book, what I propose would be fine, I believe.

Okay, I went back and did some research. On page 96 of Simply Simon is an effect called Happy Birthday and it uses a calendar/diary with the numbering scheme exactly as I outlined it above. No adjustments for the even numbered months as Busted Finger suggests. And that's the effect I've been doing for many years.
However, Busted Finger, you were right, too. In the same book, the following effect which starts on page 103 is called The Calendar Card and it describes how Simon has a special birthday card made up at Hallmark stores and then tips in the chart of card values and suits that Busted Finger was thinking of. Because of the allonone page graphic display the original numbering system betrays itself and you do have to make the adjustments Busted Finger mentions. And so, happily, we were both right. Just on different pages in the "bible" of Simon Aronson. For the record Mike Close does have a birthday diary effect for sale and it's based on the Aronson Stack but is not exactly the same as Simon's version. The original birthday diary effect was created by Alex Elmsley (Simon credits him) and uses a far simpler scheme with a relatively small batch of cards repeated over and over. Dennis Loomis

Dennis  You are correct. I was thinking of the allinone chart that Simon uses.

This may be well known, but a very nice book for this effect is the Fortune Telling Birthday Book. It costs $10 and has a fortune for each day of the year. There is also ancillary information like birth stone etc. contained in the book. Fill it in yourself using Simon's method and your favorite memorized deck.
See it at this link. http://www.amazon.com/FortuneTellingBi......11847837 Joe

Folks,
This may be a bit dated for a reply and slightly offtopic (but it's close enough in topic to post). Tonight I ran into an effect from Peter Duffie's Celtic Cabal which I recently got from VanishingInc, the effect I found is called The Birthday Book by Peter Arcane. This effect is inspired/based on Paul Gordon's Diary Effect and also involves a modified version of the PsyColour deck! I found this thread after looking up Birthday Book =) You might want to check out this PDF! K> The Celtic Cabal is available here: http://www.vanishingincmagic.com/magicd......ccabal/

I start January from the first card, Feb from the second card, Mar from the third, and so on. This way specs can see that choosing random 15ths of any month won't be the same number, and it is super easy to figure out. Month minus 1 plus day = the card.
