On Sunday, at 02:03:04 a.m. on 05/06/07, time will align itself in a perfect pattern, 2-3-4-5-6-7.
For those who slept though last year's 1-2-3-4-5-6 moment at 1:02 a.m. and three seconds on April, 5, 2006, this is your second chance.
"There are numerical patterns in nature all around us," says Edward Burger, who teaches mathematics at Williams College in Williamstown, Mass. "Some are more significant and some are more beautiful than others. And this one is a silly one."
Silly, yes. And a moment that will not come again for another century, in 2107. Of course, the times and dates will align sequentially once every year until 9:10 and 11 seconds on Dec. 13, 2014, or 9-10-11-12-13-14. After that, time will revert to its usual untidy mix of hours, minutes and seconds passing through the days of our lives.
