Except for the numerologically inclined--and a classical music radio host in desperate need of a theme to organize her broadcast hours--I'm not sure anyone took much notice of the 1/11/11 of today's date. Especially since it's been little more than a week since 1/1/11.
But I think these dates have more of a spooky novelty to those of us who grew up in the latter half of the 20th century, when they were less frequent. I remember Huntley-Brinkley noting 6/6/66 on the evening news--a rare departure from serious world affairs in those days, and with no mention of the Satanic tie-in left to our more enlightened age to discover. The next such date would have been 7/7/77, some 11 years later.
But that's the nature of numbers when the years get past those ending in 12, the number of months in the year. Whereas those born and/or bred in the 21st century, with its tiny numbers, are much more used to these symmetries, beginning with the century's first day (at least according to some) of 1/1/1. There's been at least one of these every year since. This year we have a bonanza of four: there's 11/1/11 and 11/11/11 still to come. But next year we'll just have 12/12/12.
And then that'll be it for awhile. In fact, quite a while. Until February 2, 2022, if I'm not mistaken.
