38 weeks (= 266 days) from conception to birth, 40 if you're talking to a
doctor (since they count from first day of last period, which is roughly
two weeks prior to actual conception).  Note that this is the peak of a
bell curve; "normal" deliveries can occur up to two weeks before or after
the due date.
