CAUTION: The following charts show dates and what the date was nine months (40 weeks) before that date. If you look up your birthday, you will see a date that is very close to when you were conceived i.e. when your parents were getting it on. This information can be startling to some as they see they were conceived on New Years Eve, Christmas, Father's Day, or on your Mom's birthday (gross, Dad, that's not what she wanted.)
You have been warned.
