George Finn – Calendrical and Highly Superior Autobiographical Memory
George Finn and his twin brother are calendrical savants. George can state with perfect accuracy the day of the week any date will fall on, within a second or two of being given the date. He is also able to describe accurately the weather on every day of his life. The experiences of the calendrical calculations are accessible for him most likely because his conscious Mind is not so well developed.
