9/9/09 represents the last set of repeating, single-digit dates that we'll see for almost a century (until January 1, 2101), or a millennium (mark your calendars for January 1, 3001), depending on how you want to count it. Here's how I count it: in 13 months we'll have a perfect 10/10/10, so it's really not as big of a deal as some make it.
As part of his obsession with numbers both mathematically and divine, and like many mathematicians before and since, Pythagoras noted that nine in particular had many unique properties.
Any grade-schooler could tell you, for example, that the sum of the two-digits resulting from nine multiplied by any other single-digit number will equal nine. So 9x3=27, and 2+7=9.
Multiply nine by any two, three or four-digit number and the sums of those will also break down to nine. For example: 9x62 = 558; 5+5+8=18; 1+8=9.
Sept. 9 also happens to be the 252nd day of the year (2 + 5 +2)...
But, when it comes to the past mixing into the present, 09/09/09 signifies The Beatles Rock Band – Nine...Number Nine, Number Nine, Number Nine
