This tool searches for a given birthday in the sequence of 2 billions pi digits.

`pi` = 3.14159265358979323846264338327950288419716939937510.....

pi digits sequence being infinite, we can find in it any finite sequence of numbers : your birthday, your social security number but also, the last book you read, encoded in decimal numbers..

This tool supposes that a date is always a 8-digits number : 2 digits for the day, 2 digits for the month and 4 digits for the year. For example, the search for the date 'March, 4th, 1982', will be done with these sequences,

- 03041982 in USA format (MMDDYYYY), 03/04/1982
- 04031982 in EURO format (DDMMYYYY), 04/03/1982
- 19820304 in ISO format (YYYYMMDD), 1982/03/04

Writing a date with 8 digits is a simple convention to limit the high number of possibilities. For example, for the date 'March, 4th 1982', we could also search for 341982 (3/4/1982) or 3482 (3/4/82) which correspond to the same date. For this reason, we limit the search to 8 digits dates.
