Day One by Scott Cram

Scott, thank you very much for mention my book "Gregorian calendar sheets 1582 - 2399" in the Magic Café.
Your Day One is a great book and the best (!) plot for the doomsday algorithm.
The book is very carefully and clear written. Your plot is suitable on stage for an "average mentalist" without months of training.
I warmly recommend this book!

"Day One" is Scott Cram's approach to the classic "day for any date" feat.
He developed with the goal of making the presentation appear as fast as possible, as well as simplifying the math and mnemonics involved.

You ask a spectator for the year and month of their birth, and instantly create a calendar for that month, as in this video. As soon as they finish giving you the information, you immediately start creating the calendar, with no delays!

Entire centuries are covered with less than a third of the mnemonics required by other approaches (with no previous mnemonic experience required). The only math used is a single subtraction, and even that isn't always needed.

"Day One" comes with the notes in PDF form, as well as the mnemonics animated on 4 videos, and two browser-based quizzes. You can use these quizzes in a regular browser, or even in your mobile device! As bonuses, I even include a PDF template for the calendar used, and several relevant and helpful links.
