I've been alerted to an event that will take place later this week, something that happens once and only once over the course of history. Shortly after noon on July 8, comes the moment that can be called 12:34:56 7/8/9.
It's not exactly true that this sequence of time/date happens only once.
If you follow the day/month/year convention, you can observe the same sequence next month, on August 7.
And even though it appears to be a rare occurrence, such interesting patterns aren't that unusual.
Consider these from the past:
01:23:45 6/7/89
12:34.56 7/8/90
01:02:03 04/05/06
In a couple of years we'll have 11:11:11 11/11/11.
