Yes, they cared about this a hundred years ago, too. From the New York Times, December 12, 1912:
For those who delight in that sort of amusement to-day is a day to celebrate by writing a great many letters and dating them, each and every one, 12–12–12. The sequence of the twelves makes positively a one-day stand and no more. Those who put off their writing after to-day will never again while they live have this opportunity! When again a person takes pen in hand to indite a letter with the figures 12-12-12 in the dateline, an entire century will have passed, and the earth will be peopled by quite entirely another generation. Last year there was 11-11-11, but, alas there never can be a 13-13-13, unless they change the calendar a great deal.

121212 is not a happy number.

And tomorrow is 12-13-12, which won’t occur for another century! And 12-14-12! And 12-15-12!
It’s a miracle!
