As I write this, the numbers in the current date and time will all be running in sequence from 1 to 9.
Happy 12:34:56 07/08/09 Day!
Of course, if you're American, you celebrated this just over a month ago. If you're nocturnal, you may also have been awake during another sequence: 04:05:06 07/08/09!
