Ah so it looks like about two weeks from the LMP is the
most likely date of conception. I remember looking at
the special thermometer for about a .1 degree change to
figure out the best time of conception. I guess that
was about a day before the conception time. Women have
strong lunar rhythms. I guess that's why they can tell
that nine lunar months have passed. Even if the
delivery is not on the calculated day, I would still
guess that a majority of delivers do take place close
to this day of the 9th lunar month. Millions of women
couldn't be wrong.
