How is it calculated?

Your due date is estimated by adding 280 days (40 weeks) to the first day of your last menstrual period (LMP). This assumes a 28-day cycle with ovulation on day 14.

Only 4% are born on time

Remember, your due date is just an estimate. Only about 4% of babies are born exactly on their due date. Most arrive within a week before or after.
