Katrina:

Actually, you calculate 40 weeks from the first day of the last 
menstrual period.  Conception is supposed to take place 
approximately 14 days after that date.  (So, for calculation 
purposes, one is 2 weeks along at the point of conception.)  The 
actual duration of a 40-week pregnancy is 38 weeks.

Getting back on topic, I don't think Harry's conception date ever 
crossed Voldemort's mind.  I was under the impression that the time 
between the Fidelius Charm and Wormtail's treachery was very short.  
I think the date was most likely the "first opportune moment."

BTW, where does it say, exactly, that the attack took place on 
Halloween?  I can't seem to find it.
