Weeks? Months? Trimesters? Lunar months? Days? How is my due date calculated? Your due date is calculated by adding 280 days (40 weeks) to the first day of your last menstrual period (assuming a 28 day cycle). Note that your menstrual period and ovulation are counted as the first two weeks of pregnancy. If you deliver on your due date, your baby is actually only 38 weeks old, not 40. Please remember that your due date is only an estimate. Every pregnancy is unique and your baby will come when it's ready. Be sure to talk to your health care provider about your due date. On average only 5% of births take place exactly on the estimated due date.

Natural process variation It is natural that the means vary this much, for by the central limit theorem the means should have a normal distribution, regardless of the distribution of the samples themselves. The importance of knowing the natural process variation becomes clear when we apply statistical process control. In a stable process, the mean is on target; in the example, the target is the filling, set to 1 litre. The variation within the upper and lower control limits (UCL and LCL) is considered the natural variation of the process.
