Number Sequences In Dates



OK so I have something to "vent" about.

All over the Internets I've seen some rendition of the above image, followed by the fact that at that particular time yesterday yada yada yada...

Then there is usually some sort of proclamation that "this won't happen again until 3010." Of course not! Not with those particular numbers. Don't all of these people realize that at 6:07 and 8 seconds on Sept. 10, 2011 it will happen again? Same thing at 7:08 and 9 seconds on Oct. 11, 2012.. and so on!

These types of things happen all the time, but each time it happens people think it's an incredibly rare occurrence (like the coming of Halley's Comet).

This particular example will happen every 366 days, 1 hour, 1 minute, and 1 second.

And there are a lot of others:

What about exactly 6 hours, 6 minutes, and 6 seconds later when it was 8/9/10 11:12:13?

Last year in September, we had 09-09-09, and I'm sure it also included some form of the time of 9:09:09 a.m. that day. This one also happens every 366 days, 1 hour, 1 minute, and 1 second. Hmmm, I think there's a pattern here.

We also had a "binary" day back on 01/01/10, which can be further complicated by specifying that at 8 times 16 times that day (1:00:00, 1:00:01, 1:00:10, 1:00:11, 1:01:00, 1:01:01, 1:01:10, 1:01:11, 1:10:00, 1:10:01, 1:10:10, 1:10:11, 1:11:00, 1:11:01, 1:11:10, and 1:11:11) it is expanded to 12-digit binary (including the 0 which is left out before 1 o'clock times). And what'da'ya' know, only 9 days later the exact same thing happens again. By the way the same 16 32 occurrences happened in 2001, too, and will also happen this coming January - Not to mention that in October we'll have 10/01/10, 10/10/10... you get the picture.

Until the year turns to 2013, there will be lots of these funny sequences of digits when including the month. Likewise until the year turns to 2032, there will be a number of these sequences that include the day of the month.

And I'll bet no one even realized what was going on back on January 2, 2004 at 8:16:32.
