My birthday is Dec. 25, 1962. What day of the week is it? Some patients of savant syndrome can tell the day of the week for any date in the past or future with amazing speed. The reason why they have such incredible ability is still unknown, but we could anticipate they are not doing so time-consuming computations for that. Then how? The text tries to give an example to tell the day of the week in a few steps of calculations.
