In school, you might have learned that Pi equals 3.14, or perhaps you encountered a more precise approximation, such as 3.1415 or even 3.1415926535. However, the true value of Pi continues indefinitely:

For this experiment, we take the first 1 billion digits of Pi and use them to find the first occurrence of a birthdate, formatted as YYYY-MM-DD.
For instance, if you were born on March 14, 1996, we search for the sequence 19960314 within these 1 billion digits.
We find the first occurrence of 19960314 at digit on position 213,151,795:
...528767888093997910291996031404885581224813797303...
The digits immediately following the birthdate are used to calculate the geographic coordinates of a location on Earth.
By extracting the next digits, we derive the latitude and longitude. In decimal format, with five digits after the decimal, the latitude becomes 48.85581 and the longitude is 2.24813. These coordinates point to a location near Paris, France. This is a sacred location for any individual born on March 14th, 1996!
