September 17th 2009? Your conception date would be roughly December 26th 2008, give or take 5 days
It depends on when the due date was, rather than when the baby was actually born. But, if the due date was June 5th, it makes the conception date roughly September 11th, give or take a few days. However, it's difficult to accurately say when a conception date was. Therefore, I suggest you talk to your doctor or midwife about it.

December 12
The approximate date of conception was December 24th
Mid September. However if you really meant you had your baby at term June 6 2006 rather than that is the date an early ultrasound gave you then it might be off by 3 weeks either way as you cannot calculate backwards as accurately as healthy babies can be born any time from 35-40 weeks after conception.
