Sadly, I did not sleep right through it, because I got up to pee and couldn't get back to sleep. Still, I hadn't considered the ramifications until now. Now, in military time, 12:12 AM is actually 0012. So 1212 12-12-2012 is yet to come.
And, of course, 1:13 PM Jan 13, 2014, is really 1313 13-13-2013.
