The program shown in SMBC 2922 (March 22 2013), implemented in Python.
Given your birthday, this program calculates a reasonable date for your conception and then parsesWWikipedia for the 'most likely' event that inspired your parents to have unprotected sex.
To execute, just download this script, navigate to the file via command-line and do $ python conception_connection.py
Working speed okay for current dates and dates in the 20th century, becomes slower if you go far into the past or the future. You have been warned.
