In honor of the day, here is a site that lets you search the first 200 million digits of pi.
Numbers up to seven digits long are virtually certain to be in there. By the time you get to an eleven digit number, the odds drop below 1%.
So my street address, my 5-digit zip code, and my PIN are all in there -- not just once, but thousands of times each. Even my 7-digit phone number appears 20 times. (With the area code prepended, my 10-digit phone number doesn't appear at all, at least in these relative few first 200 million digits.)
Today's date, 03142018, appears one time, beginning at the 150,741,354th digit of pi.
