Calendar calculating, the only savant skill Daniel was willing to perform in front of me, turns out to be so simple that it really shouldn’t impress anyone. Savants like Kim, who can tell you the date of every Easter in the last thousand years, seem to have internalized the rhythms and rules of the calendar without explicitly understanding them. But anyone can learn them. There are several very simple calendar calculation formulas, published widely on the Internet. It only takes about an hour of practice to become fluent with them.
