Does the headline above mean anything to you?
It represents a date and time. Today, December 12, 2012 at 12 minutes and 12 seconds after 12 noon.
That very moment in time will be 12-12-12 12:12:12. (Some will argue that it actually happened just after midnight. But using a 24-clock, 12 after midnight is actually written as: 00:12. So there!)
Who cares right?
Perhaps no one. But I do. I want to remember where I was at that moment in time because a date and time with all the same number will not occur again for a very long time.
For those of you trying to calculate that date, I'll do it for you. It will happen again on January 1, 2101 at one minute and one second after 1:00 am. That's actually 88 years, 19 days, 12 hours, 48 minutes, 49 seconds after the 12-12-12 12:12:12 moment.
So, unless you think you'll be around on 01-01-01 01:01:01, you might want to make note of where you're at, who you're with and what you're doing at this once-in-a-lifetime moment in time.
