It was both a Palindrome and an Ambigram! Reads from L to R, R to L and also upside down. It happens a few times with a year only, but first I've seen with date, month and year. Know of anymore other than 1961?

But it all depends on which format is used for the date.

I've always thought that the number 9 was somewhat unique. I'm not sure of the mathematical term for it, but it is unique amongst numbers in that whatever 9 is multiplied by, you can always obtain 9.
So, for example
2x9=18 and 1+8=9;
3x9=27 and 2+7=9;
4x9=36 and 3+6=9 and so on I believe until affinity!

Put a 6 in front of 9 and turn 180° and get the same number.
