I missed it. I was busy. At 12:12:12 on 12/12/12 I should have done a dance or something. But I missed it. For 12:12:12 A.M. I was sleeping. For 12:12:12 P.M. I was at a lunch meeting.
This will be the last chance for alliterative dates until 2101 (for 01/01/01). Probably won't live to see that day.
My son graduated high school in 2007 and of course they had James Bond tie ins for their graduation ("class of 007"). In 3007 I doubt anyone will remember James Bond so this was the one and only time in human history this will happen.
Of course, if the Mayans are right, 12/21/12 is going to be a bad day for all of us.
Did you observe 12:12:12 today?
