Is 09/09/09 so Special?

I was going through some of the articles on this special date and some of the facts that caught me..

Pythagoras - noted this number as unique for its specific properties..

• This is known to any math student.. That the sum of the two-digits resulting from nine multiplied by any other single-digit number will equal nine. Like: 9x5=45, and 4+5=9 so on..

• Multiply nine by any two, three or four-digit number and the sums of those will also break down to nine. Like: 9x62 = 558; 5+5+8=18; 1+8=9.

• This was little creepy, but that's the fact. Sept. 9 also happens to be the 252nd day of the year (2 + 5 +2)..
