What is the format for the birthday string? YYYYMMDD? DDMMYYYY? MMDDYYY? Different results for each...

The lowest pi date for a living person I could find was "05132000" which appears at number 596

As the author says only 63% of dates are in their system so far (i.e. in the 1st 200M digits)

DDMMYYYYYY : "The string ******** did not occur in the first 200000000 digits of pi after position 0."

DDMMYY : "The string ****** was found at position 174,544"

MMDDYY : "The string ****** was found at position 956,548"

YYYYMMDD : "The string ******** did not occur in the first 200000000 digits of pi after position 0"

Didn't check my birthday, but I did spend a few minutes putting the numbers 00-99 into it to see which was furthest in. The top four are:

68 – 605 Digits In
76 – 569 Digits In
77 – 550 Digits In
18 – 424 Digits in

I also remember that 57 and 00 were pretty high, but a few others may have been higher than them.

A more interesting question with this data is "How far into pi is the furthest in two-digit string?" rather than "What is the furthest-into-pi two-digit string?" Another interesting question is "What is the probability of it being so far in, assuming the digits of pi to be random?" or alternately "How far in would you expect it to be, using a probabalistic analysis?"
