If a baby had a normal gestation period, and was born on May 17, 1973, what's the most likely conception DATE?

Ovulation would most likley have happened on August 24, 1972. If it was a normal 28 day cycle with ovulation occuring on th 14th cycle day... The first day of the last period would have been: 8/10/1972.

See: http://www.due-date-calculator.com/

Only 4% of babies arrive on their due date. 2/3rds are born within ten days of their due date. so you will have to give or take a few days to a few weeks depending on if that person was born on their due date!!!

You can't pin this one down. A normal gestation period is not a specific number of days or weeks, but an approximation. The same is true of conception. No woman knows when she's ovulating, and there is about a 5-day window around ovulation in which introducing semen into the female reproductive tract can result in conception.

The best you can do is find an approximate date.

August 10.

August 24, 1972

You have to take into consideration that everyone is different. You need to know how long the womans cycles lasted usually they are 28 days but not everyone is...Also ovulation is different in everyone. So...you can have an "about" date but theres no way to give you an exact day.

Middle of August the previous year.

9 months before duh!
