Makes me wish I had lived in the year 1111. Imagine it being 11:11:11 on 11/11/1111! Of course, they probably didn't have the technology to measure time accurately enough back then, and might not even have used the same calendar. Ahh well.
On a more serious note, I was quite anxious about 09/09/09. The attacks on the World Trade Center occurred on 09/11, which is similar to the US Emergency Services number. 999 is the UK's Emergency Services number. I wonder whether the recently foiled aerial terrorist attack on Britain was planned for today, 09/09/09. Scary to think that we could all be reeling from a horrific attack right now, had the terrorists not been stopped.
