The 40 week gestational period, estimated delivery date, and gestational
age are calculated from from the 1st day of the last menstrual period
(LMP), but the pregnancy generally lasts 38 weeks (9 lunar months, each
lunar month is 29.5 days) after conception, which is usually estimated
at 2 weeks after the 1st day of LMP. Fewer than 5% of deliveries are
actually on the calculated delivery date.
