Estimated date of confinement (EDC) is a medical term used to indicate the expected delivery date of a pregnant woman. However, this term is being replaced by other more inclusive and less medicalized expressions. Some of these synonyms include due date, expected due date (EDD), estimated delivery date, delivery due date, or simply the date of delivery. It is important to understand that these are all just estimates and can be subject to change based on a variety of factors. Regardless of the term used, the birth of a child should be celebrated as a joyous occasion for all involved.
