The Due Date Calculator estimates the delivery date of a pregnant woman based on her last menstrual period LMP , ultrasound, conception date, or IVF transfer date. Related Pregnancy Calculator Pregnancy Weight Gain Calculator.

The due date, also known as the estimated date of confinement, is an estimation of when a pregnant woman will deliver her baby. Due dates can be estimated using a number of different methods, including the last menstrual period, ultrasound, conception date, and IVF transfer date.

The default for this calculator bases the calculation on a woman's last menstrual period LMP , under the assumption that childbirth on average occurs at a gestational age age of a pregnancy calculated from the woman's last menstrual period of days, or 40 weeks.

Although there is some debate regarding when pregnancy technically begins, whether at fertilization of the egg conception , or when the egg adheres to the uterus implantation , gestational age does not vary based on different definitions of pregnancy since it is based on LMP. In terms of gestational age, pregnancies typically last between 37 and 42 weeks, with 40 weeks often being used as an estimate in calculations. Thus, the due date is usually estimated by calculating the date that is 40 weeks from the start of a woman's LMP.

Estimating due date based on ultrasound involves the use of soundwaves to look inside the body and compare the growth of the fetus to typical growth rates of babies around the world. It is a simple process that can be performed quickly and easily, that has no known risk to babies, and can be an accurate estimate of the due date early in the pregnancy. Using conception date to estimate due date is similar to using the last menstrual period, except for a difference of about two weeks in the point of measurement, based on the timing between the last menstrual period and the date of conception.

When using in vitro fertilization, the estimation of the due date is generally more precise than calculating the due date based on natural conception, since the exact transfer date is known.

It still uses the average gestational age at birth of 40 weeks from a woman's last menstrual period, as do the other methods. In the case of IVF, however, the due date estimate can be made based on LMP, day of ovulation, egg retrieval, insemination, as well as the date of the 3-day or 5-day embryo transfer.

In this calculator, the embryo transfer date is used. Generally, the point within the 37 to week window at which the baby is born is not a cause for concern. Babies born between weeks, weeks, and weeks are considered early term, full-term, and late-term, respectively. Under normal circumstances, babies born within any of these ranges can be healthy, though full-term babies generally have better outcomes.

These ranges are important as a reference for doctors to determine whether or not any action is necessary. For example, if a woman goes into labor too early at 33 weeks, doctors may stop labor to avoid a preterm baby that can have a host of health issues due to underdevelopment. Conversely, if a woman has not gone into labor after 42 weeks, doctors may induce labor. One possible complication of allowing the pregnancy to proceed beyond 42 weeks is that the placenta, which is responsible for providing nutrition and oxygen to the baby, can stop functioning properly, while the baby continues growing requiring more nutrients and oxygen , which would eventually lead to a point in the pregnancy where the baby can no longer be adequately supported.
