Today is 12-12-12, the last major numerical date using the Gregorian or Christian calendar for almost another century. The next time three numbers will align as they did on 9-9-09, 10-10-10 and 11-11-11 will be on Jan. 1, 3001, or 1-1-1.
"It's just a cute day," said Underwood Dudley, a retired professor of mathematics at DePauw University in Greencastle, Ind., and author of "Numerology."
"Maybe we ought to look out for the end of the world," he said. "Other than that, it's just a number. The delusion of numerologists is that numbers have a power over events, but they don't. Just because it's 12-12-12 doesn't mean anything will happen. It would happen anyway."
But Scott Petullo, a Las Vegas-based numerologist who turned his expertise in handwriting analysis and astrology from a hobby into a profession, is a believer, even though he knows others might view him as a "new-age whacko, charlatan or snake-oil salesman."
He said the day can be "auspicious or challenging, based on other factors, such as how the patterns in a person's comprehensive charts harmonize with the date."
