Even more — seven AM, seven minutes and seven seconds: 07:07:07 07/07/07. That won’t happen again, at least for 12 more hours. It would make James Bond envious.

Of course, we recently had an event like this at three minutes and four seconds after 2 AM on the sixth of May of this year, namely 02:03:04 05/06/07.

I mentioned something similar last year, on April 5 at two minutes and three seconds after 1 o’clock, the time and date was 01:02:03 04/05/06. What is unique about this current phenomena, however, is that it doesn’t change if you live in Europe or someplace that uses dd/mm/yy format.

These kind of things happen more frequently than you’d think. I remember when I was a kid, being impressed that pennies that were dated 1961 had a date that looked the same upside down.

    Dear Bill:

    Numbers, numbers, everywhere numbers. Does it all add up?

    Perhaps you can offer a comment on or explanation for the significance of Square Root Days.

    You and I go back a ways. The first Square Root Day we experienced as recent graduates from U C Berkeley was 09/09/81.

    Then we had 1/1/01 and 02/02/04. Next up is 03/03/09. Let’s hope we are still compos mentis on 04/04/16, 05/05/25, 06/06/36, 07/07/49, and then 08/08/64, the first Square Root Day you and I would share as Centegenarians. I would be a youngster of 106 (and 12 days), while you will be under 110. . . .

    What does it all mean? We all count on you for insightful historical commentary. Take satisfaction in knowing you are a factor in keeping us all sane and informed.
